I'm glad you're putting your son first! He deserves that.

It really could be just the meds adjusting in your body. Hopefully anyway! It also might take a while even after the adjustment for you to actually adapt to a stable mindset and emotional range - you're so used to extreme ups and downs!

Like.... My hypomanias are quite mild and short-lived. But when I'm out of one, I feel like a boring old zombie for awhile.

You could also be in a depression. Since I've been on meds the past two years, I'm finding the depressions that crop up to be REALLY confusing. The medication takes the edge off, including some of my normal tell-tale signs for myself. It's actually a lot more of "indifference" for me when I'm in one as opposed to "oh gawd I want to be dead, I hate myself". The last time I was in one I actually wanted to toss out my meds because I got pissed off at being confused..... was a stupid thought, but it was like "at least if I wasn't on these meds I'd FEEL it properly and would notice how to deal with it instead of being this!". The thought processe is a bit hard to understand, but regardless, it was definitely a stupid thought that didn't really make sense even though it was totally clear in my head at the time.
