Did I permanently damage my car?

[vouvoune]

ok, so I was driving in third gear with my mind somewhere else and stopped at a grocery store which you have to access through a short, stiff incline.

I slowed down but did not realize I was in third gear stalledi n the middle of the incline with people around and a car behind me so it happened very fast.

I restarted it and pushed it pretty hard since I was on the incline (still not getting that I was on third gear) and stalled again...I then FINALLY realized that I was in third gear...I parked and it STUNK (like burned rubber) in the whole parking lot...I went home (5min away) and the car really smells...

Could have I caused permanent damage? if so, what is is likely to be...
I feel so bad! My poor little car!
