I've been diagnosed with MDD for about 4 years now. I'm 23F. 
I've tried taking my life before, almost dying and ending up in a coma last year. I've always stayed in bed often, unless I had to work, and work time was the only time I spent out of bed. Sometimes, I can't even get up to shower for multiple days. I was living with my grandma before, and she actually understood and didn't mind me staying in bed as long as I still went to work or therapy and took my meds. 
But, I had to move out of her home recently, due to my sister having a baby and nowhere else to go. So, I moved in with my aunt. She really doesn't understand me at all. Everyday, she comes into my room and nags me about staying in bed or my room too much. She keeps telling me that I HAVE to get out and do things. She even sends me these articles about how bad it is for you to stay in bed, how to "cure" depression, etc.
I hear about it EVERY. SINGLE. DAY. She has people come over and gets offended that I don't want to go hang out with everybody. She says that I'm rude and lazy. I still get annoyed with her dang articles. She acts like it's so easy to just "not be sad" and "get up and do something!"
I've tried so many antidepressants and I still can't find any motivation or desire to get out of bed. 
What helps any of you to get up when it feels impossible?
