AG, seems to me I've suggested on several different occasions that you need to start by controlling your mood swings. Until then, trying to work on anything else is just added pressure to you. You may believe the positive you absorb while you're on the upswing, but it all goes down the tubes when your mood hits bottom.
About all you need to get a firm grasp on right now is to know there is a way to control your moods and that you CAN accomplish it. Work as hard as you can on that and leave the rest alone until you are more stable emotionally.
I haven't checked and neither do I know what your dx is, but more than likely, people that have the same dx as you could give you better support than those of us here in this forum.
I'm with Pat. It's really difficult to know what kind of help you need or what we can say to help. Nothing seems to work.
