I know im a little older than you, but what I tried this week was to just not do as much, not let myself get as tired. Like instead of trying to do hour walks, do shorter walks. And I ended up not sleeping all day Friday, and getting some housework done (albeit sitting down), which is more than I've done on a Friday after a fsirly active Thursday (haircut, lunch out, t appointment, some walking) in a long time. But also it took me since August to build up to this. I've never taken vacations, because my mother always wanted to come with. So I just never went anywhere, unless it was like a work convention. T keeps telling me I dont know how to self-regulate. I say I have two speeds, fast and off. Is that your issue too? My parents never helped me work towards goals of any kind. They always thwarted them, either at the beginning, the middle, or the end.
