bullying

so i have multiple experiences with HIGHLY toxic friends. One of them actually got a few of her other friends to beat me up....for no reason. I was hella weak and submissive as a child, so it was really easy for kids stronger than me to take advantage of that. I also did everything people told me to do. Another friend (a few years later) would like step on my feet super hard (which would leave bruises. Sometimes I would limp), force me to do things i didn't want to do, and would force me to buy her snacks from our school cafeteria. (Those snacks were expensive so I ended up spending like 80 dollars each month.) After that last experience I kinda got more cold and untrusting towards people. I also speak up more and people know kinda not to push me around.
