Meg - it could be that you're just SO USED to problem solving that you instinctively just feel like you SHOULD be doing more. It's like the Codie fight-or-flight reflex, lol. We find ways to keep trying to make things easier, smoother, better because we CAN & because what seems like a small, manageable task to us is a big obstacle to less healthy people around us. Just like he got used to you doing FOR him, you got used TO DOING for him, kwim?
Could also be that you just want to be DONE & be able to walk away at this point & are willing to do whatever it takes to make that happen asap.
I would examine my motives/emotions that are driving my need to "do" & chew on that mentally for a while. When you figure out what "drives" it (fear, obligation, control) you'll be closer to understanding why you do it & how to change that reaction for yourself if it's something you think requires changing. JMHO!
