I vote get help as soon as possible. Sounds like Bipolar to me. I waited until I was age 63 and my marriage just about went out the window. Believe you are much better off (I certainly was) getting medicine and doctor which was a psychiatrist for me. And the right psychiatrist because after a while I had to change. Also if you think you can stop medication, you're only fooling yourself, and your brain will loose ground and you will fall back into that dark hole.
