<human>: No idea where else to turn, I have created a throwaway, and will ask you guys for advice. 

My mother is objectively a very bad person. She has verbally abused my brother (23) and I ever since our father died 9 years ago. 

She has attempted physical abuse on few occasions as well, she once threw an ashtray so large and heavy at me, that it could easily have broken my jaw had I not evaded it.

 The most extreme thing she has done, was to not leave the house a single time for 4 years, while getting shitfaced on red wine every day.

Now she has become very ill from the intense alcohol abuse, and she has lost control of her bowel movements, she can hardly walk, and is very angry that she can no longer drink. She just recently called me a faggot who were up to no good, yet she is very much in need of care 24/7 and just bailing on her seems quite difficult. My brother is serving military duty in the other end of the country helping as much as he can. 

I currently study in France, but had to go home to assist my mother. Should I bail hard, or help her, even though she does not like me and lets me know quite often?

Could you distill the essence of the text into 1-3 sentences?
<bot>: My mother didnt leave the house for 4 years, called me a faggot, needs care because of illness, should I help her or not?
