Undiagnosed bipolar from 13 to 32. Initial diagnosis was schizo/mood disorder during high school. Then from 20-30 graduated to just clinical depression/ anxiety. At this point there had been multiple OD attempts and sporadic SH episodes. I've been on every antidepressant possible. Nothing helped. I began to feel like a guinea pig. At one point I was on Nuedexta. 
While on that med I had my worst manic episode to date. It climaxed into another attempt, a rubber sock retreat, and finally and proper diagnosis. 
Bipolar. 
It made sense. 
I finally felt seen. 
So then began another journey of med tinkering. 
Had some hypomania in between as we adjusted and switched things around. But I can safely say I feel stable and have been for at least a month on this medley:

Morning meds: 75mg lamictal and Adderall 30 mg XR (as needed, I'm severely ADD but aware enough to recognize daily stimulant use can trigger mania)

Evening med: Seroquel 100mg

Seroquel has been a lifesaver for my manic insomnia. 
I had this irrational fear of falling asleep and losing time. It got so bad that I couldn't even be near my bed. I know it's strange, but I was afraid to go to sleep. Seroquel saved me in that department. I was literally running on 2 hours at the most every night because I would drag my bedtime out til sunrise.
