I've done the same and can empathize. I was diagnosed when over fourteen years ago, and it wasn't until this year where I finally accepted it and started therapy. It's weird, I too notice how my mood changes from one to another and I do over stress for no reason at all. Therapy does help. To have someone there to listen openly to what you have to say is very helpful. I thought that friends and family would do it, but to have a third party from a different point of view does help. It does take a while to become of aware of your emotions without overheating to things. There are the good and the bad that comes with this illness. Calming down the emotions is what I find tricky, but it last for a short period of time and you overcome it.
