A good friend of mine (an excellent guitarist) was truly messed up by what is known as "British justice" and after many years of sufferring, was referred to a psychiatrist and ended up on medication which sent him off in a very bad direction. Fortunately, through the help and support of a bit of what is called alternative therapy, mates and family, he quit the medication and slowly but surely got back to a place where life is not all bad. Based on his experience (not fair to judge them all I know), a psychiatrist is the very last place I'd go if I wanted to understand myself. As Dave says, be wary of who you check out. There are, for example, great hypnotherapists and very poor ones. There are tons of "self-help" books out there- the advantage is that they are cheap and you can put them down (or in the recycling) if they don't do it for you.
