Pooh....... I may come off as an old crab (I'm 52, which may simply make me a middle aged crab)..... but I would ask you to think about renaming your post; "How can I feel more secure?". ( I'm teasing you a little here.....don't actually do it.

) Allow me to explain. You see, to me....... you are doing EVERYTHING; working two jobs, I assume parenting duties, household tasks, and the huge job of caring for someone and all while fretting that you aren't doing enough.
Just because a person has HCV does not make them an invalid. It sounds to me as if you are doing PLENTY; perhaps more than your fair share. You may even agree; I am only basing my opinion on information which you provided.
As I mentioned, I am 52, have HCV, work a job, also work a part time job, and have my three kids living with me (15, 17, 21). I provide parenting (I'm a single parent), housekeeping, driving assistance in school, and am rebuilding my house. I even provide a
few hours of work on this board per week. So just because people have HCV should not prevent them from also contributing. I can't speak to the level that your boyfriend is disabled by HCV, but many of us are able to work. If we are given care, most of us have a level of gratitude for it.
I'm glad that your boyfriend is in recovery. If he wants to keep the HCV at bay he may find that working a 12 step program may help him stay clean. I have attended al-anon for 5 years. One of our deals is to try to keep the focus on ourselves and "let go" of wanting so much (approval, gratitude, and non-stop adoration

) from other people. I'm being a little tough on you because I feel as if I have been in a similar place. There was never an end to how much I had to work. We end up trying to equate our value with how much we work, or how much we DO for other people. It IS a strength and a positive feature in a person...... but it is possible to overdo it. It becomes a character defect if we let our kindness and capacity for giving (and giving and giving) run wild. If it is out of balance we just work, cut ourselves off from life and run ourselves into the ground. And for what? For others approval........ Uh oh......

It sounds to me as if you are a caring person. Maybe if you worked less you would have more time for the kids and boyfriend. Maybe if you are working two jobs the kids may actually need you more than the boyfriend.
My apologize if this comes off a little gruff. My goal would be to get you to have a little more rest, fullfilment of your
own life objectives and enjoyment out of life.
Best wishes,
Willy
