Stuck in a hard spot.

I'm going to try and keep this simple, but basically my dad put himself in a hard spot by volunteering to go on furlough back in 2020 because of covid. He then chose not to go back to work and milk his unemployment until he ran out. He needs a knee replacement, but couldn't afford to get it done cause he didn't have insurance and while he was on unemployment he made too much for medicaid. Well now he's completely not working hasn't been collecting money for like 4 months. I've told him about jobs hiring that would be good while he has a bad knee, my uncle has helped him with a few job leads, we've all told him how needs to go about getting his  knee fix because now he is on medicaid. And he hasn't. So this is all 100% on himself at this point. Well he's now 2 months behind on insurance so my aunt text my sisters and I to see if we could all help. I'm a sahm so we only have 1 income and we get no government assistance at all. My husband's income is literally all we have. I feel terrible because we really can't afford to help. My heart wants to because it's my dad. But apart of me is also like no, this is all on him. We all have our own bills to pay. We have 2 kids to provide for. Our money is tight especially at this time of year my husband did get a nice bonus but we used it to pay for his vasectomy out of pocket because our insurance wasn't going to cover it that has been planned for months in advance. We were orginally going to have them bill us but when we got there the lady said if we pay full price now it'll actually be cheaper. So since our Christmas was already done and bought for, my husband went ahead and that. I just don't know what to tell my older sister and aunt who are better off in life. They both have 2 incomes, they don't have little kids. I'm basically stressing over someone else's bill when I shouldn't be. Our bills are paid. I love and care for my dad, but he has so many things he bought stupidly with his unemployment that he could now sell and yet he refuses to. On top of that my husband is basically like yeah F that, he needs to figure it out, which I don't disagree with at all. I just feel stuck because it is my dad.
