No, they do not get to shut this down just by writing pre-existing in a letter.

That word scares people because it sounds final. It isn't.

In Michigan, the real question is not whether you had anxiety or depression before the crash. A lot of people did. The question is whether the rear-end collision on I-94, I-96, M-59, or some other Michigan road made it worse, triggered a major relapse, or caused a new level of dysfunction that needed treatment.

That is where these claims live or die.

Why they send that letter

The insurance company knows mental health claims are harder to prove than a broken wrist or a herniated disc on an MRI.

If you were already barely hanging on before the crash, missing shifts at a warehouse in Romulus, an auto supplier in Dearborn, a plant in Warren, or a furniture shop outside Grand Rapids, they will try to build the whole case around one ugly sentence: you were struggling before, so this isn't from the crash.

That is lazy analysis, and sometimes it is straight-up bullshit.

A rear-end crash can absolutely worsen existing depression, panic disorder, PTSD symptoms, insomnia, agoraphobia, or suicidal thinking. Michigan insurers know that. What they are really saying is: prove the difference between your before and your after.

The part most people miss

You do not need to prove you were perfectly healthy before the collision.

You need to show that after the crash, something changed in a concrete way.

Maybe before the crash you had anxiety but could still drive to work on I-275.

Now you have panic attacks every time traffic slows near a bridge overpass or construction barrels stack up.

Maybe before the crash you were depressed but still making it through your shift.

Now you cannot sleep, you are vomiting before driving, you freeze when a car comes up behind you, and you got written up for missing too many days.

That difference matters.

Insurance adjusters love vague files. They hate detailed ones.

What actually helps your claim

This is the rare situation where specifics matter more than emotion.

Not because your suffering is not real. Because the insurer is looking for any excuse to call it old news.

So the strongest evidence usually looks like this:

• records showing what your mental health looked like before the crash, and what changed after
• therapy, psychiatry, primary care, or ER notes that tie the symptom spike to the collision
• documentation of new meds, dosage increases, work restrictions, missed shifts, or failed return-to-work attempts
• notes showing driving fear, nightmares, flashbacks, crying spells, isolation, or inability to handle traffic after the wreck
• family or coworker observations that you were functioning one way before and another way after

That last part gets dismissed too often.

If your sister is the one now driving you to appointments in Wayne County because you cannot get back on I-94 without shaking, that is not fluff. That is evidence of lost function.

The police report is not the main fight here

A lot of people get stuck on fault.

They keep rereading the crash report because the other driver rear-ended them in stop-and-go traffic, maybe during freezing rain, maybe on black ice, maybe in one of those ugly pileup conditions that hit west Michigan when lake-effect snow comes across and visibility drops fast.

Fault can matter in parts of a case.

But when the insurance company says your panic attacks are pre-existing, they are often moving the fight away from the crash mechanics and into your medical history.

That means the issue becomes medical causation.

Not just who hit who.

"But I already had depression" is not the end of it

Here's what most people don't realize: insurers act like pre-existing means unrelated.

It doesn't.

If the crash aggravated an existing condition, that aggravation can still be part of the claim. Michigan cases have been fighting over this for years in one form or another. The insurer may owe benefits tied to treatment that became reasonably necessary because your condition got worse after the wreck.

The ugly part is that they will comb through old records looking for every mention of panic, antidepressants, missed work, or prior counseling.

If your chart from two years ago says "history of anxiety," they'll wave that around like they solved the case.

But a history is not the same thing as your current level of impairment.

Someone can have longstanding depression and still be functioning enough to work, drive, shop, and handle daily life. Then a crash happens and everything falls apart.

That collapse is the issue.

Why anxious people get punished by the claims process

Because the system rewards paperwork and punishes shutdown.

If you are severely depressed, you may not answer calls.

If you have panic attacks, you may avoid opening mail.

If you are overwhelmed, you may miss therapy, delay filling prescriptions, or fail to correct bad insurance notes.

And then the carrier uses the mess against you.

They will say you are noncompliant.

They will say treatment gaps mean you must be fine.

They will say no one connected the symptoms to the crash, even though you were too flooded to explain it properly in the first place.

This is where it gets really cruel.

A person whose mental health got wrecked by the collision is often the least able to build a neat little file proving it.

The wording in the letter matters

If the letter says your symptoms are "subjective," "not causally related," "not accident-related," or "due to prior psychosocial stressors," that usually means they are laying groundwork to deny payment for treatment, replacement services, wage loss support, or other parts of the claim tied to your mental health decline.

That language is not neutral.

It is written to box you in.

Especially if an insurance doctor or paper reviewer never really dealt with the fact that after the crash you stopped driving, lost hours, could not tolerate traffic noise, or started spiraling every time you heard tires skid on wet pavement.

What makes these cases stronger in Michigan

The best Michigan mental-health-after-a-crash claims usually tell a very plain story.

Not a dramatic one.

A clear one.

You were functioning at one level before the rear-end collision.

Then the crash happened.

After that, your treatment changed, your work changed, your driving changed, your sleep changed, and your daily life got smaller.

That is the argument.

Not "I never had problems."

Not "the insurance company is evil."

Just this: I was struggling before, and after this crash I got much worse in ways that can be tracked.

That is a real claim, even if the letter in your mailbox makes it sound like you are making the whole thing up.
