Worried

I knew this was coming, but i didnt think i'd be this scared. I just got told yesterday that i was to be booked into the hospital on may 4th to have my tonsils removed. They have to do a prep a week before hand to see if im ok with the procedure. Im so scared. This is strange for me, im not usually one to fuss but one thing that i truely despise is ... needles. (Strange seen as i love being peirced) I guess its different though, having one needle to peirce your skin, another that will stay in you and inject you/take blood. Even the thought of it makes me cringe. They will have to ut me under a general anesthetic which means a needle being shoved into my hand. :'( Ouch. I cant say im looking forward to it much.
