I think the trick is to remember that the instability in moods and depression is rooted in a problem with brain chemistry. You know how you feel and it is not for anybody to tell you how you feel. if you feel that taking meds will help then do so. I find that keeping a blog and writing down my thoughts and feelings helps to get them out of my system. The reason is that you are forced to analize what you are feeling and thinking in such a way that you think through it very clearly. You are also then able to look back over days, weeks and months and look at how you saw things then and how you see them now. I find that looking back this way help me a lot because I am able to resolve current issues in relation to previous issues. Our memories are just too unreliable to do this mentally.
