got the loan, finished pre-ops requirements, got my date..freaked out!!

So, I was approved for surgery loans with my mother and step father's help... finished my pre-op requirements, got my surgery date for July 2.. NOW I'm kinda freaked out because I'm afraid i'm going to have a difficult time paying back my loans.  I am stressing about this to the point of anxiety attacks and major meltdowns!  I have looked forward to this for soo long, done all my research, bought all the books, etc. 

My sister and my dad say that I should follow through with the surgery no matter what because its a surgery regarding my health and not for an unneeded item such as a luxury car.  I mean, to be honest my credit already sucks because I tried to get my bills in order by going through a debt consolidation company.. but I do not want to ruin my mother and step father's credit!  I am TOTALLY freaked out. 

Relax and take it one day at a time.

This is an awesome opportunity!!!  Be thankful that your parents are helping you with the loan, and go ahead and have this surgery!  I had been fighting my insurance company for a year and a half, and then I was laid off.  Now I have NO health insurance... and because I am worried about financial stresses, I'm very afraid of gaining even more weight!!!!  Go for it!!!
