Sick and tired of being sick and tired

I think it would be safe to say that I caught some kind of cold/sinus viral infection around the end of October and I haven't been free of it for longer than a few days in between long spells of not being able to breathe....not cool. I'm not really sure what the deal is. My whole life I have been the one that never gets sick. My whole family would get the flu or strep throat or whatever and low and behold I would walk through the fire unscathed. So it has me completely puzzled that 1. I got sick in the first place and 2. that I didn't get over it in less than a week. OK, it's not a completely mystery; the fact is, I am surrounded by children all day and it's beginning to take a toll on my immune system. If I had to base whether or not I'm going to keep working at the day care on one thing, the whole always being sick thing is enough of a reason for me to put this job behind me. It's sad, but true. I've almost forgotten what it's like to breathe without decongestive medicines, not have eye drops, a bag of cough drops and nasal spray on hand at all times and not go through a box of tissues a week. It will be a blessed day indeed when I can wake up in the morning and be able to breathe.
