heartbroken over my final grades

I had a very traumatic adolescence/middle school experience where I was a victim of violence and abuse. I was a total mess back then. The abuse got better in high school but I didn't realize I was absolutely traumatized from previous years. I developed severe depression sophmore year that has continued. I'm medicated now and doing better but my grades from before I was medicated have ruined my gpa. I graduated with an 83%. I'm going to college but I could've gone to a better one. A lot of my friends did a lot better than me and it's so embarrassing. My parents couldn't care less and I can't talk really talk to anyone about this. I hate that my circumstances have ruined my life like this. Idk why I'm posting this. I'm just so heartbroken.
