Feeling bad again

I haven't posted in quite some time. I wish it was because I felt so good that I was out living my life, but such is not the case. I had some good days, yes, but they were all tinged with anxiety. I'm now in a very bad place again. Last week I got a urniary tract infection - a real one this time, not like the false alarm for which I was prescribed cipro. I knew I had it, had all the symptoms. So I was prescribed amoxicillin. I took it faithfully. I called out of work the first day because my anxiety was so high that I was pretty much immobilized. It got worse from there. I stopped taking it at 6 and a half days because I felt much like I did after the cipro. My arms and legs ache and are weak, my anxiety is out of this world, my face is numb, and my stomach is in knots. Today is the second day I've been off it. I had hopes that I would feel somewhat better, but I don't. I woke up feeling like I couldn't breathe properly, near panic. I have to work today and am dreading it. I haven't gotten in the shower yet because I'm afraid to be wet and naked. Just typing this, my arms are weak and sore. God, how can this happen again?

Also, and update on the pet situation. My little dog Mini had to be put to sleep the week before Thanksgiving in 2009. She got diabetes somehow and went down hill in about 5 days. By the fifth day she could barely walk so we had her put down. Then in February my cat Pickle got to the point where I felt she needed to be put to sleep. She spent hours trying to go to the bathroom on my bed, pushing out bits of bloody urine. It was hard having her put to sleep. I really miss her. I sometimes still think she's going to climb up on me at night. She was a wonderful cat.

Guess I'd better get my butt out of bed and brave the shower. If there is a god out there, would you mind making my life less hellish?
