In ANY event, it's just a truck,
People are important, stuff is just stuff.

Wait for the adjuster to give an estimate. Maybe get an independent estimate or two if you think that one is low; and go from there.
The OP is in that weird time between the accident and the repairs when you feel like you should be doing more. Your world gets upset and you're waiting on other people to act (insurance adjusters, body shop managers, rental cars, parts suppliers, etc.).
It's inconvenient. It upsets your routine. It seems like a big deal and in the end it's just STUFF.
I've watched dozens of people go through this and I've been through it. More often than not it turns out OK. I've also seen people take these events and make them more complicated than they need to be.
Your car got bent.
They're going to give you some money to replace your car or repair your car.
Life will go on. Make it as frustrating or non frustrating as you wish.
