Self Esteem with building connections with others

I have personally had a hard time these last few months with real personal connection and also with partners I’m in my first year of highschool and the world is really a scary place, having fake friends and even other people not trying on purpose to hurt you still can. Backhanded compliments and *** really hurts I have had friends burn me and even my date to homecoming date who I had a crush on for two years left me and honestly I feel broken it’s like the more connections you make and the more rejections you get breaks you down like a brick wall and it lowkey hurts so I respect all of y’all on here and thanks for letting me get my feelings out.
