Car got repossessed last night - how screwed am I ?

I just graduated college. COL too high salary too low. I know I’m stupid and really messed up but how screwed am I? I just called the bank this morning and going to spend my whole check to get the car back. If I get the car back will it still show on my credit? Do I have to let insurance know even if I get the car back in 2 days? Will I be stuck not being able to buy a house / rent a decent apartment for the next 7 years?
