Tired of Being Sick

I'm now on my 3rd set of antibiotics in 2 months.  The doctor also has me doing 5 breathing treatments and 2 inhalers a day.  It has made me so exhausted.  I feel like I'm shaking half the time and have a headache the entire time.  After I'm finished with everything, I'm supposed to go get tested to find out what immune deficiency I have.  Once they know what kind, they can place me on a medicine to help strengthen my immune system.  Until then, my doctor made me quit my job because, at the moment, I'm catching everything the children have.  Hopefully, after I'm placed on a medication, the doctor will say that it's ok for me to go back to work.  However, it is nice being able to come home after school to work on homework...except for this week.  This week I've been coming home and going to bed because I feel so awful.  Hopefully, this will all get worked out very soon.
