Try and Not Think about it

Its really bothering me that i'm getting more and more upset about how my friends treat me. I went to a basket ball game a few weeks ago and the person i went with, ditched me to go sit with someone else, it really hurt my feelings and i was crying but not in a way that my friend can see it. I would never ditch anyone even the person i went somewhere with, how could you do that to a friend? I've realized that this person isnt going to change anytime soon so the best i can do is remember what my counselor told me and is to learn the word accept so i've accepted that this friend will continue to do what shes doing. I've expressed how much i'm a good friend, i would do anything for them, again look how i'm treated. I havent been taking my medication lately, and i need to get back on track with that.  My feelings are getting hurt every day now and i cant talk to my mom about it, i cant talk to any of my friends because we're all friends with the same people and in the town i live in, people know if they are being talked about.  My mom and i got into a fight. She didnt like what i was wearing, i dont wear skimpy trampy clothes, just a shirt and jeans stuff like that, my mom is all about the matchy matchy. She told me what i was wearing basically made me look not pretty and my self esteem points just went down. I have been teased so many times by my looks , it really doesnt help if my mom critiizes me. I'm starting to question if i'm really that ugly?
