It's been a bad day

I just found out today that I may not be able to continue my treatment for my multiple sclerosis. Why?? Because the treatment is making me sick. Last month during treatment I got sick and vomited all over myself, and today during treatment I got severe chest pains that they had to stop my treatment again. I am pissed because I loved the treatment and it took me so long to get approved for it. I am sort of at my wits end today. It's getting harder and harder to walk around with a smile on my face, hell its getting harder and harder to walk at all.
