Help Drew and his Mother get back on track

My name is Drew. I'm a self-taught digital artist and disabled. I have Schizophrenia, IED (Intermittent Explosive Disorder), and PTSD. I cannot work, so I am on a fixed income due to my disabilities. For others, I know there is the strength to overcome this kind of struggle, but right now, I am unable to do that. I can't change that right now, but I am trying to.

Right now, I am living with and taking care of my mother because no matter how bad my problems are, hers are more important. She is all I have in this world that matters, and I am failing her. She's a lung cancer survivor, had both her knees replaced but can't walk without a walker anymore, and she can't see her doctors without a wheelchair. She's declined mentally and physically slowly since my grandmother passed away in 2016. We're relying heavily on her disability and credit to get us through this hell because my check has been $800 short for most of this year. I've gone without food sometimes because I am making sure she can eat and be healthy. I've been struggling mentally and missing some of my doctor appointments to make sure whatever problem she has is solved because she is more important than I am. I want to give her the best life I can. That's all I want. I am failing.

She's a good mom, but it's past her time to be a protector for me, and now it's my turn to protect her. I don't want to ask for money or help, but I have to swallow my pride and do it anyway. I have fallen behind on my bills. I am $800 behind. Been that way for almost the whole year. I've had less than $200 in my bank at the beginning of each month to help us live on for the whole month for a long time because something always comes up that I have to fix. Every time, every month. I find a way to survive somehow, but I am at a loss right now. I don't see a path forward right now. I see homelessness on the very near horizon. I need help to get back on track. I need help to take care of my mother. I've had a truly shit year, but I am doing everything I can to make hers end well. I have a budget planned, but I haven't been able to use it due to lack of funds. I don't want Christmas gifts or fancy things or anything like that. I just want to go into the new year with our bills straightened out. There will never be an amount of money that will fix our every problem. That is a fantasy I am aware is unattainable... but anything can help. Please help me so I can take care of my mother.

Thank you.
