I am suicidal, should I find new friends?

I have two friends. Anna was always making fun of my crooked teeth by saying, "Is your mom into beastiality? Because you look like a horse." or, "You can't expect a boyfriend with those horse teeth." She always said it was, "dark humor" or that she did it, "out of love". It made me feel awful though so I constantly told her how it made me feel but she would always say the same excuse. I finally got serious with her and told her to legit stop and I feel I got a dirty look from her and was told, "Okay, I get it" while I had not even finished my sentence. There have been times where I am suicidal and I call her because she has encouraged me to talk to her in the past and she talks to me or texts me and than the next day she is making fun of me by saying, "Hey Anna I am suicidal", and than afterwards tells me "Sweetheart, I deal with depression everyday. Deal with it"
During times I have bad mental brake downs, she will be nice and one time she wiped my tears while I was crying.
Jose has recently been acting strange. Earlier this year, he jokingly said I had the face of a rapist which upseted me, he has said that I am the stupidest in the group along with Anna when somebody asked "who is the stupidest" and said that I act like the world revolves around me and that every little thing upsets me, despite the fact I have told him some VERY serious stuff before. He also said I was "sensitive" because I was upset about what Anna was saying. He once hugged me when I was crying.
