sweety, you have to put your well being first sometimes and this sounds like it may be one of those times. I have been in a similar situation with my brother, who is a mooch. I finally got fed up and told him he has a week to find a job or he has to walk. This got his attention but I did have to hound him every day.

I hope things get better for you, it is hard when someone takes advantage of you, especially whne you have MI. Feel better!!
