Nobody got seriously hurt but I can't stop shaking — do I even belong here?

You absolutely belong here. I was in a low-speed collision a while back — barely any damage to either car — and I spent two months unable to merge onto the freeway without my hands going numb on the wheel. The brain doesn't care how bad the damage report looked. It experienced something terrifying and it's trying to protect you. Please don't minimize what you're going through.

What you're describing — the hypervigilance, the sleep disruption, the intrusive replaying of the event, the freeze response — those are textbook acute stress reactions, and they are a real physiological response, not a character flaw. Your nervous system got activated hard and it hasn't fully come back down yet. This happens to people after minor fender-benders all the time, not just serious crashes. The therapy appointment is exactly the right move. In the meantime, try to be patient with yourself the same way you'd be patient with a friend describing this to you.

One practical thing: make sure you document how you're feeling with your doctor before that therapy appointment if you can. Psychological trauma is a real injury and if anything comes out of this accident legally or with insurance, having a medical record that notes your mental state early on actually matters. Don't just white-knuckle through it quietly.

Not legal advice, but just so you know — psychological injury like PTSD and acute stress disorder is compensable in personal injury claims in most states. It doesn't require a broken bone. If you're seeing a therapist and a doctor about this, keep those records. What you're going through is real and the legal system recognizes it as real too.

Just heads up — if you end up dealing with the other driver's insurance, do NOT describe yourself as 'fine' or 'okay' to the adjuster. I know it feels weird to claim psychological harm when you weren't hospitalized, but adjusters absolutely use those casual comments to close out claims fast and low. Let your doctors and therapist do the talking.

The fact that you recognized something was wrong and booked therapy before it spiraled into something worse — that's genuinely huge. A lot of people push it down for years. You're already doing the hard thing. Week and a half will go fast and you've got people here in the meantime.

Genuine question, not trying to be harsh — have you talked to your regular doctor at all since the accident, or just scheduled the therapist? Asking because some of what you're describing (the shaking, the sleep issues) can sometimes have a physical component too, especially if there was any head movement involved in the impact. Might be worth a quick checkup just to rule things out before that therapy appointment.
