lifes little up and downs

well sometimes i like i am just going completely crazy and i dont know why. i have a genarally good life and yet there are some many thing in life that seem to still annoy me like me and everything around me and i dont know why. i should be happy because i have a wonderful boyfriend his family is awesome and give me a sense of family that i havent felt in a long time and maybe thats what is getting to me but it shouldnt it should make me happy but for some reason every thing around me litterally annoys me. so why do i feel this way i just dont know maybe i will figure it out maybe i wont but who knows maybe i am just going crazy and just dont know how to stay happy.
