It's hard to always put your health first. But we have to, we really have no choice in the matter. I've been struggling with making committments as well, I usually drop out of things because I either have pain or am too tired. I've tried to make my friends understand this, and the ones that stick around when I cancel are the ones I want to hold onto. It's so difficult to balance it all, I wish you luck! I don't really have much insight, I just know what its like to feel like a bad person because I just cant do it because of my health.
