Taking Care Of My Grandmother

It has recently been brought up that I should go back home to Alberta to take care of my grandmother. I initially brought it up myself to my mother because no one else would and I didn't like how family was treating her already since her illness. My grandmother has wetlung, and her kindeys had failed her over the year from medications. She has to take dialysis every week, and might have to move to Edmonton because our town doesn't have a dialysis machine. She is herself still, and can walk. She just can't really do too much to strain herself cause she's weak and get bloodclots if she does too much. So I would basically be a caregiver as in; cleaning, cooking, shopping, ect. In a way I don't mind, well I didn't at first. And she;s grown to the idea of me coming home. But I started to get scared lastnight, and this morning. I live in Toronto the last three years, and myself have been needing therapy. I've gone through a lot in my own short life, and it hasn't been easy. My family is made up of a lot of selfish people. My mother is an educated woman who has spiraled into a drug addition the last ten years, I left her to live with my grandmother for a little while when i was 15. After that I moved everywhere and anywhere running away from things. I lived in a foster home till I was of age, and eventually moved to Toronto to get away from my family and friends who felt like they were holding me back. i've spent my life moving from palce to place taking care of someone. I'm just scared of it. Scared to leave my bf, were not sure what will happen if i go. he has never left the city, and still has another year in college. My friends out here, my therapy. I feel like I am trading my life I worked so hard to get to open up to, and it makes me angry that no one else is stepping up to help my grandmother. everyone is wanting me now to go, but won't go themselves. there is just so much going on in my head right now.
