I definitely know how you feel. About ten years ago, I had to leave my job due to physical and psychological conditions. probably two years later, I was put on social security disability. For a long time, all I did was sit around the house doing nothing. This really didn't help my socio-agoraphobia. I wouldn't even walk down to the mail box. My wife did everything for me because she thought that would make things easier for me. It only put me further into the hole I had dug for myself.
Anyways, five years ago, my mother-in-law (who was a major *****) fell in her kitchen and banged her head off the dishwasher. Long story short, she was finally released from the hospital but now had the mentality of a sweet early teenage girl. Also, while she was in the hospital, she lost her left leg do to an infection and poor circulation. My wife and I moved into her mother's house and, for four years, I took total care of her 24/7. At times, she would get bratty and feel like I was her servant who was to run to her side whenever she wanted a cookie. A lot of times I would get frustrated with her attitude and we would get into a yelling match but, most of the time, we were friends. A year ago, just before her 69th birthday, her heart stopped during hemodialysis. The hospital called me but we didn't get there in time. When she died, she took away my mother-in-law, my friend, and my way of life. I was so lost for the longest time. Still am at times.
But, the point is, we had to work together to form a relationship that met both of our needs. I understood that she needed around the clock attention and she had to understand that I had my own life I needed to attend to as well as her's. She had to learn a level of respect that she had previously never given to anyone. Because we both worked to meet the other's needs, we went from two people that couldn't stand each other to being very close friends. Talking, not yelling or guilt tripping, accomplishes a lot.
