What you are going through does sound a LOT like mania, tree - mania does not necessarily feel good, especially when it includes racing thoughts and irritability (common symptoms of mania)! SAM-E may very well have something to do with the way you are feeling if it is known to cause manic symptoms!!

The last part -- stop working so hard, go in to T and cry -- that sounds like a good idea. You've made so much progress by telling H and your friend. I think it's okay to take a support session now and then as long as you're continuing to make progress on the CSA stuff. But don't let crises keep you from talking about it.. sometimes that can be a temptation, or something that just happens without our awareness.
