I was re-living my old days as OD went down the toilet and I too wish I could go back to certain aspects of the past, but I guess that would change who I am today and who knows if that would change me for the better or worse? Anyway I am constantly jealous of my friends and I hate it. I am single all but 2 of them are married with kids. I am 33 and have endocrine system problems and other medical issues which will make it hard for me to have kids and the older I get the harder it will get and I think I may never have children as I always dreamed. I can fully empathize with you and being envious of your friend.
