It's kinda scary how much of your identity gets wrapped up in the things you own until, and you don't realize just how much it does until it gets taken away from you.
Something similar happened to me when I was your age. It was then that I decided to work on improving myself more and hit the weights hella harder, spent more money on my appearance and worked harder for the next car. It was a game changer for me. I still have a soft spot for that car, but I have better things now. And the satisfaction in earning them myself is irreplaceable.
Keep your head up and act like it doesn't affect you. Be positive. The more you act like it outwardly, the more you will believe it yourself, and you will grow stronger much faster.
