I Dont Know Why

I dont know why i say the things i do .I dont know why i do the thing i do.I can only sit and pray and make them better.I cant take back the things i say and do. But i do feel bad i do feel sad I just want a good life and dont know what to do..My heart is telling me what to do but my mind is telling me what to say. just wish I knew how to say whays on my mind and do what i have to do...
