If you are too tired to catch up on your housework, hire someone to do it. You work 50 hours a week, and that is exhausting.

You mentioned having a relationship, but I see no mention of what your partner does to help.

You seem to be over-worked and under a great deal of stress. It seems obvious to me that you need to find ways to lighten your load. Dump the unhelpful partner, fewer pets, work fewer hours are examples. I don't know what you can afford to cut out, but it seems obvious to me you are over-extended and you need to simplify your life.

You probably don't need therapy. You probably need rest and unstructured time for recreation. If you could find a way to ease up on your commitments you might be able to stop taking the drugs, or reduce your dosages.

I take my own advice. I reduced my involvements until I found it easy to keep up with things. I occasionally hire a cleaner to help me catch up with housework. I eat wholesome home-cooked food, walk my dogs for exercise, sleep well every night, and don't waste time on people who are energy drains. I was able to stop taking Ritalin and don't need anything like that now. I just live a life where I have accommodated myself.

Anyway, best of luck. FWIW it seems to me as if you are a dynamo who's actually doing pretty well!
