How do I comfort my sick relative?

I have a relative who has been sick in bed for over a year now.

She ruptured some discs in her back, has chronic fatigue and fibromyalgia, recently was diagnosed with diabetes, and generally has poor health and very very low energy.

It’s very difficult to see her in this state. For over a year now her world has pretty much been her bed and the occasional trip to the bathroom or kitchen.

With this said, it is very hard for me to comfort her. Her doctors have been saying for months that she needs to start pushing herself just a little to get up and move around, walk down the street and such. (We live in a neighborhood very close to some beautiful lakes, a dog park, paths with nice bicycle and pedestrian lanes, etc).

I try to encourage her to get better by actively doing something but it seems that she is so tired and worn out she has no energy for anything.

Sometimes, it’s hard to have compassion and I feel like a terrible person because sometimes I lose patience with her. Occasionally I’ll come in the room and she’s left food everywhere and has been watching DVD’s and left them scattered about the room. I usually have to pick them up because I can’t ask her to.

It’s hard to constantly clean up after and care for someone when it looks like they’re making no progress. My patience has run out and I fee like a terrible person sometimes because I don’t have the capacity to care for her. I’m a college student with a lot going on in my life and I can’t be there for her as much as she needs (she’s obviously lonely because she doesn’t really see anyone all day).

Do you have any suggestions or similar experiences to share?
Thanks in advance.
