Sick of being sick.

I am having so much trouble moving... physically and in the finding a place to live sense.
Last night, I went to a show with some friends and on the way in, I sprained my right ankle (the one I am in PT for to begin with- and the sprain was diagnosed by my physical therapist today) and about halfway through the show I got so nauseated and dizzy and I felt like something was stabbing me in the lower left side of my stomach. (the stabbing pain also happened Sunday morning while I was at church with some friends)
Today, I ate a small, plain-ish sandwich and felt horrible.
Tonight, I am attempting some chicken and angel hair... and that will be my last meal for a while, as I have to start prepping for Wednesday's colonoscopy, which will be done under full anesthesia.
I am in so much pain.
I don't know what to do.
I have very little time in which I will have a roof over my head too... I am searching every day and getting nowhere. No matter what, it is going to cost money that I don't have. If I wind up on the street, I will die. I can't lose my kitties. I am so scared.
I really can't even express it properly.
I am forever grateful to the people who are trying to help me, in every sense of the word.
Thank you.
