Getting kicked out of my moms house

So I am 23 and I originally moved out when I was 18. I moved to a different state than my mom about 2 years ago.. and 3 months ago I got hit by a car. I was in the hospital for almost 2 weeks and I could no longer work. I started to very very quickly drown in medical debt that I could not pay ontop of my usual rent, utilities, food, etc.

I didn’t know what else to do and so I called my mom and asked if I could come down and stay with her while I recover. I changed my doctors to one closer to her and had a consultation with my original doctor before leaving and she had told me that I’ll need at least 3 months of recovery before I’ll be able to go back to work. I don’t really want to explain the details of my injuries, but I’ve had multiple surgeries so far and I’m on an insane amount of painkillers.

I’ve now been living with my mom again for 1 month. We usually have a very good relationship. We call each other all the time and it’s not a rocky relationship at all. But now she’s getting frustrated with me and told me I need to get a life and go somewhere else. I was SO incredibly confused because again… I am LITERALLY bedridden. I cannot work, I can barely shower by myself. I asked her if there was something that I did and she told me that she just wants her space again…

She’s making me feel like such a burden on her. We never had any fight or anything. I’m not loud or rude to her ever! I didn’t know what to say to her so I just plead my case and asked if I could please just be supported for a few more months till I can go back to my job. I’m on medical leave with my job so I will be able to go back to that once I am recovered. All I’m waiting for is the doctors approval.

I have no other family members. Dad died and I’m an only child. There’s literally nobody else I can stay with-rent free. I know that it’s a burden but it’s only for a few months while I heal.

I had a doctors appointment with my new doctor yesterday and he told me that I should be able to go back to work in 2-3 months. But I don’t think I can ask my mom to keep me for that long.

I don’t know what’s wrong with her and why our relationship is all of a sudden so rocky. Am I being rude asking her to help me out?? I can’t help but feel like she’s in the wrong… I’m only 23. And I just wanted help from my mom for a few months…
