I hear you on trying too many things at once! I know I also have trouble knowing whether things are good or bad because of what I just changed- or hormones or the weather or changes at work . . . being female is complicated . . . *sigh*
BTW- I've also had that typically male "That is an epic turd!" moment occasionally. I think that since they're less frequent now, there's more time for them to build up? Who knows.
Good on you with the wall pushups! Have you thought about weight lifting? I'm finding I really like it, and it helps with my mood. But any movement is movement in the right direction!
