Why do o get so anxious When I talk to people even with family. Is so stressful to me?

I have had it since I was a. Teenager and now that I’m 27 is even more stressful being a grownup.

I grew up being the only child until I was 13 years old. My parents would always fight while I was dealing with my own issues at school like bullying since elementary and worse in middle school. I would skip class and school bc of that and never knew I was being bullied by my appearance. Due to not having nobody to talk to I made mistakes and talk to older man and I got raped.

I told them and I took time away from school and got therapy. But my issues were always there. When I was 18years old my parents got divorced and I was going to independent school but eventually I dropped out bc I had terrible social anxiety ( they always thought I just didn’t want study but in reality I was having mayor anxiety and was depressed. )
