Feelings

Do you ever feel as if you keep your true thoughts and opinions to yourself just to keep the peace? I only ask because lately I seem to be doing that a lot, all to keep other people happy. However in doing this, I feel like all the things I'm leaving unsaid are building up inside me, and I'm waiting to just explode from it all. I guess I don't like confrontation, and most of the time I'd rather agree with whatever is being said, just to stop upsetting or annoying anyone. Probably not a good thing to do as in the process I just seem to sit and stew in my true feelings. For example this week, I've been feeling quite let down and disappointed after someone who promised they would be there for me basically hasn't been and although I've tried confronting them, they just don't understand or care enough to ... care really. I really don't know what to do for the best, and I'm really hoping this whole situation ends soon, one way or another.
