Welcome, and let me just say, you've definitely come to the right place. Even from my own very short experience here, I've found that just about everybody here has dealt with/are dealing with/want to learn how to deal with these kinds of issues in their life. You'll find widely varied advice, yet all of it is sure to be earnest and thoughtful. For starters, you might want to try telling us all some stuff about yourself and some of your circumstances, perceptions, problems, and goals, and then we can go from there.
