Cultivate worthwhile friendships and sever 'friendships' that are a waste of time

This ones complicated. It’s about identifying toxic relationships and finding true friendships. I think I have found my first true friend, there’s a quote that says true love is hard to find but true friendship is even harder, and i can defineately relate to that. I found my high school friends are too judging and bitchy for me. I’m too compassionate and sensitive to tolerate that stuff and i was often the one on the recieving end of it so I’ve almost completely severed my relationships with them. It’s taken me 5 years to completely accept that they are bad for me but it feels good. I have also made a friend at uni, we have so much in common she is as sensitive and compassionate as me and accepts me for who I am without judging, I’m a bit scared that she will end up hurting me but I’m willing to take the risk.
