I'm a fighter...right?

:( my thoughts are what's keeping me from being happy. I fucked up my one year with my boyfriend because I had unknown sadness. ever since then I just stopped hiding myself and the thoughts are hitting me so much harder. "since the 21st you two have been drifting" or "he's stopped calling you while he plays" or "he is acting different" these thoughts hurt me so bad. I realize he is busy and has a life! I know these things but these thoughts just want to break me until I give up! :( he is my happy ending and he says the same so I remind myself over and over. I can be happy. these thoughts I can't let them ruin my happiness!!
