I will also second the idea of talk therapy. It is a hard thing to do, but you reap the rewards in the long run. Some years ago, I needed to get through a rough spot. A friend (a pediatric psychiatrist) recommended a psychiatrist that was very good: she did talk therapy and was into all kinds of alternative therapies. I am the nightmare customer for doctors because I am not a believer in pills (or herbs), so we tried a number of alternatives between pills and types of therapy. For me, cognitive behavioral / talk therapy worked best. <life would be easier if I could enjoy some placebo effect.>
