Excited but also scared

Hi everyone.  I'm so glad I found this site.  I am having gastric bypass on the 22nd of this month.  It seems like it is coming so fast.  I am excited to start this new healthier and happier chapter of my life but I am also getting pretty nervous.   Not for the surgery itself, but for the after.  I can't help but wonder if I am going to be strong enough to do this.  I know deep down that I am, but I can't seem to stop the fear.  Did anyone else feel this way right before surgery?  Any advise?  Thanks for listening!
