Hi Bex! I saw this thread not too long after you posted it and have been meaning to get back to it but... you know how life goes.
We're the same age, and I totally hear you on the "I'll be 26" thing. I'll be 27 before we start ttc. I've always wanted to be a young mama, and this will be pushing it.
So how am I coping? Right now I'm just focusing on how good life is now, and working on bringing myself to a place where I'll be the best mama I can be for when it IS time for my baby to come. Enjoying the time I have with my partner, playing with all my friends' babies (What is it when you're already struggling with the idea of trying to avoid, and EVERYONE around you is getting pregnant? I mean, SHEESH! :LOL ) and enjoying all of the things I won't have as much time for when baby comes. And I cry, and mourn, and remind myself why we're waiting.
Hope this helps. Good luck to you, and feel free to PM/email me if you need a shoulder to cry/vent on, cause I'm right here with ya sister.
