Please help my mom!

I'm from Russia and my English is not perfect. So I will try my best to explain my situation.

Me and my mom live in Kazan which is the city in Republic of Tatarstan in Russia.

My mom is in need of medical treatment. She's 58 years old, she is type 2 diabetic, group 1 disabled person. On insulin since 1999. She currently has several serious complications due to diabetes. Among them: diabetic neuropathy, overweight, high blood pressure, blindness, weak kidneys, both legs have a diabetic foot, which is why she cannot walk at all. She need pills and periodic injections and intravenous droppers to help sustain her in healthy condition. Right now we can only afford the pills. Her health can get worse in a few months if we don't continue her proper treatment.

The problem is I got into debts after my father died. I started to take small loans. But over the past year the debts kept increasing. I had to take new loans to return the previous loans. Because those loans need to be returned in full the next month with big fees. I started to take extra shifts at my job. It helped for some time until it wasn't enough. And it was exausting. I tried the second job but it didn't work out because they paid very little, it wasn't enough to return the loans. Right now I need to return the full amount. If I don't, those small financial firms have legal right to sue us and take our property including the apartment where we live. For some time our relatives and my co-workers were helping us financially, but right now they no longer can help us.

UPDATE

Last year I hired lawyers to help me get rid of the debt. They said that they can lower the amount of the debt. But the financial firms need to file a lawsuit first. But they still haven't done this yet. So I stopped paying the loans and the current debt is now $12000 because of the penalty fees. The lawer's services is not cheap so I have to pay monthly about $330. So we are still struggling to continue the treatments. Ideally I want to pay out all debts completelly to avoid any harassment in the future.
