discouraged my sickness depressed?

T
I have HG,  I've been off work for 3 months and I have been in hospital. I am heavily medicated and suffering from a digestional disease and now I am constipated, sick, fatigued and in pain. 
I feel like I'm sick 24/7 I am sick 30x per day and. Ever get a good night sleep. I just don't know what to do.
I'm getting sad from being home alone and I am so overwhelmed and discouraged
