Do I have real friends?

My friends leave me out of stuff they do and they make hurtful jokes about me. I never told them that they hurt me because I don't want them to get mad at me. Today, one of my friends told me I was a crybaby. I cry very easily but that's just me. They even know that I am under depression and low self-esteem. Now I only have one friend left but I just don't want to be their friend anymore because I'm going to high school and I want a fresh start. They even started a rumor about me crying because I only got one reward at our certificate assembly. That was not true because I was crying about the fact that I couldn't get into a good college with enough certificates. I have a sensitive personality and they hate me for that. Should I come crawling back to them tomorrow or just let it go and be on my own?
