Trust me I understand. I believe most people would feel awful staying home by themselves more than few days.

I'd honestly feel depressed if I never went anywhere. If you worked all day though you wouldn't be alone. You'd be too busy. Perhaps too tired.

I am very confused on what you mean by no one cares. How exactly you want them to care? To support you? Pay bills? Etc adults usually fend for themselves. Most adults don't live with others and no one supports them. When people are sick they see a doctor but they don't expect anyone to take care of them. Most people don't.

Do you live in the country where noMental health help is available? If you can't work, tell your doctor that you want to be on disability. If you legimitately unable to function see your doctor about it and get treatment

But trust me, waiting for others to fix your life will not work. You'll wait forever.
