Holding it all in

Agh. What's wrong with me? I have communication problems. I hate hurting people's feelings. I hate being controlling. I hate being annoying. So much so that sometimes I don't SPEAK UP when I need to. And then I get upset. And no one knows it but me. And it's my fault. I really need to learn to communicate to people how I feel about things, because I'm making myself miserable. Please pray for me on this topic! Thanks! :)
