How should I deal with this situation?

My high school experience was absolutely horrible. I did nothing but go on computers, study, a few forced extracurriculars, and barley left my house. I was incredibly stressed the whole time, got pretty depressed, and struggled with sexuality the whole time (I finally came out 2 years ago). I had little to no friends, I lost most of my friends from distance or declining of my sexuality, which made me even sadder. I had a unique passion that demonstrated through my common app that helped me get into a really good school, but I feel traumatized by my previous couple of years. All they were were arguements, lunches eaten in the bathroom, struggling with sexuality, struggling with weight and body image (exercising a lot more), computer over usage, and never leaving my house. I am going to college and want to recreate myself. Should I just forget about this situation and move on. It feels hard but if I also don't reflect at all from this situation I am never going to learn from it.
