All started in early childhood and elementary

I've had this issue since childhood. It happed with my three bestfriends in elementary 2nd grade. We were very good friends, we laughed and had fun with each other. I dont remember too much because it tried to forget. One day they stopped hanging with me and I found out they talked about me and made fun of me. I told them a bit of personal stuff. My family also had things to do with it, wasnt too good of a household back then. I tried again and again and again but the trust was lost, I trusted too easily. Now I dont really trust anyone because theyll end up taking bad about me or just leaving. I never once blamed them for anything, I always felt I kinda deserved it tho but idk.
