My biggest problem. I care way too much about everything. I care about the way I look, I care about what people think, I care about being clingy, I care about getting hurt, I care about hurting feelings by saying an outright no.
I've finally learned to let go. To let go of those who never cared. To let go of those who stopped caring. To let go of those who only care when it's convenient for them. To let go of those it hurts to hold on to.
