Shared deed prop taxes

My brother and I inherited our mom's house, and it was decided that I could live there until my death so I wouldn't be homeless in my old age. I have nothing, he has everything.

The problem is I thought we were both responsible for the property taxes and insurance, but he's making me pay the full amount bcuz I live here, but if I have to keep paying the taxes from savings, I'll end up that way anyway. I'm afraid if I press the issue, he'll force the sale of the house, and then I'll be forced to move. I'm 63 and disabled with COPD. I can't physically move. Please help! Thank you!!
