Ive been where you are. In fact, I have days when I would give anything for those highs. I realize that normal isn't depression. the impulsive behaviors I had on my high cycles is now replaced by new activities, new hobbies.
I can sit for long periods reading, crocheting, writing, meditation, and yoga. These activities would never have accomplished effectively when I was untreated. I relish in my accomplishments of wellness. Hope that helps.
