How do you get over childhood bullying which has significantly impacted your social skills?

As the title says. I have been bullied from secondary up untill highschool included for a myriad of reasons. Like being too much on the phone, being overweight, not having friends, liking star wars, for a girl I liked and also for being too emotional and crying a lot, for a silly jump I did once, how I looked in pictures, how I looked with a beanie once and a bunch of other things. This bullying and isolation in this part of life has severly impacted my social skills in a worst part. I don't even have friends now, I find it hard to open to people, I am chronically online (as in a lot of times on social media/discord), I cut off everyone from high school and so on. This bullying has not helped me in anyway, I am still somewhat overweight so yeah. I still think almost every night about this, I find it hard to vent to parents about it and I also find it hard to open up to therapists. I feel left out of every friend group and it sucks big time and I am afraid it will be hard to find love, to make memories and to have stories to share to future kids and grandkids

What do I do in this case?
