I'm going to be starting uni in September. When I was in years 7 and 8 I was bullied by my best friend and my ex friends. We were best friends for 5 years before that. The situation caused a lot of anxiety and I went to counselling because of it. I'm now past the situation and was discussing my oast experience with my sister and I brought up how sometimes the thought of coming face to face with her again makes me so anxious my heart races. My sister said I should block her as a year ago she followed me on insta and I followed her back. My sister also told me to not worry and focus on my path. I hung out with some friends today and they mentioned that she will be studying in the same uni I will be this year ans will be studying a course of the same field as mine. I really don't want to see her again. What id she asks why I blocked her. What if I end up being friends with her again I have a tendency to forgive, get too attached and they ditch me.
