Life, in MY nutshell

I turned 31 a few days ago, and its really starting to bother me.
It's funny, I never really had those "wow, I'm getting older" feelings...until now.
Maybe its because I'm now "officially" into my thirties, or maybe its because of the health issues with my heart. Maybe its because it seems that everyone around me is starting a family and I'm unable to. I do feel like my biological clock it ticking double time now - something that I never thought twice about before.
*sigh*
I guess I will just have to continue dealing while the medical professionals in my life try and "fix" me. Lets hope they "fix" me before my clock stops ticking.
