Hey
heres something that might help you thru ....I have used it to help a few people in your situation..and its really simple .
It's the fear of the thing that has you ... The fear of something is ALLWAYS way harder to deal with than the thing it's self , Your imagination is a very powerful thing and you can tell yourself and convince yourself it's going to be hell ... but when you do it you will see that the fear if it was worse than having it done .
for an example ... try and think of something that you dreaded having to do .... and then you did it and thought " hey i thought this would have been worse "
the fear of the pain is way worse than the actual pain !
So go for it bud ..I'm proud of you and i'm sure they will do all they can to make you as comfy and pain free as they can .... they will no doubt use all the expencive shit ..seeing as your paying for it
Good luck man
