Phew, cowgirl. Keeping everything for crossed.
As for the whole weight/fitness/happiness thing.
I am a stone heavier than when I had my DD seven years ago. BMI 29. The difference is though I am a damn sight fitter than I was.
I started running over a year ago, couldn't run round the block to start with. Eventually I can now run 10k, completed a natural obstacle course race, and military training days.
I have not lost weight. I didn't do it to lose weight or change my diet. I did it because after MCs I wanted to focus on something for me!
I ran. I am so much fitter than I've ever been. I believe it also took my mind of the 'issues'!!
Funnily, I got BFP after my two toughest months, Feb this year was the icy cold eliminator race and the training day. March I got preg.
I think if you want to do anything, exercise, swim, dance, learn to sew, you do it because it gives you time out, and time to focus on something completely different, and gives you a whole bunch of satisfaction when you've done it. Not doing because you want to get BFP, or else your mind is still not turned off! Hope that makes sense!!' It does to me, I just wanted to switch off from it all.
Maybe talk to go or trial nurse about weight, but don't get hung up on it. Be healthy, be happy.
