Help

My mom initally had a form of cancer. I took over all levels of care. Transporting to doctor weekly for radiation treatments, medical appointments, radiologist, oncologist and anything else. I travelled to work over an hours distance, each way. She eventually recovered (in remission) and went back home but i still have to oversee and take her to all medical appointments because she cannot do it. I have other siblings but nobody helps. She recently hurt herself and is back with me again. I am trying but i am so burnt out. She could barely bathe properly before but since getting hurt she cannot bathe much at all so i have to do it. Problem is she does not like bathing and has an "i can do it myself" attitude. I feel so burnt out, overwhelmed and very depressed. I feel terribly awful because i cannot do it again. I am struggling this time. It doesn't help that my mom and i have never been very close
