Wonderful father who needs help!

This is my dad. He is an amazing father. My parents were divorced and he took on raising three children on his own and a fourth child that wasn't even his own every weekend. No questions asked. From burnt dinners to shopping for bras with two girls, he somehow made it through, all while battling manic depressive disorder. In and out of hospitals being treated for his disease he still did the very best that he could do.  He made sure that my siblings and I had everything that we needed growing up. After the divorce he even sold his business that had been in his family for over 50 years to raise us. He also wouldn't date due to woman complaining about him having custody of his children.  At just 34 years old we lost our brother, his only biological son. It hit him really hard and he never really recovered from it.  Due to current circumstances that family members have put him in, he is struggling to pay his bills and fix his house to sell it so he can move to a senior apartment or a small condo. He is battling stage III kidney disease and his manic depressive disorder and can only handle so much. I have stepped in to help but can only afford so much on unemployment.  I love my dad more than anything and he has given up so much for me and my siblings. I just want to help him out somehow. Please help!
