Not sure what to do

I finally received my vials of methotrxate and as I was reading the insert, that it is a chemo drug, just really stood out to me.  And boy, do the needles look big even though I know they are not bad.  I'm going to be really ticked off, if my hair falls out, it's one of the few things left that I feel vain about.  I still can't start it quite yet as I need to get I think 3 days worth of folic acid first.  Today still wasn't a great day, I can't shake this fever and everyday it's another symptom.  I hate being down on weekends the most.  At least during the week, my hubby is st work and I don't feel as if I'm missing out on too much.  This weekend is the big draft party and I really wanted to go to it.  All I can hope is that feeling better is around the corner.
