Heavens, yes, Virginia Marie. You are not alone on this by any means. Next Tuesday, I will have been on HRT for one solid year having missed about 5-6 days in the summer when I "hit the wall" and gave up. Janet Lynn read me the riot act, talked some sense into me and got me back on track.
Like you, I'm an older gal ... a tad older than you, I believe. Well, I did not expect much, but, oh, did I hope for great breast development. Amazingly, it's happening! Yes, it's slow. Yes, it's asymmetric. As you can see, I don't have much; however, it IS happening. All told, I'm happy. Though I'm unlikely ever to have much endowment, at least I have some.
I've had to lay off of going to L.A. Fitness for the past month or so due to job-change circumstances, and that's a bummer. However, I'll get back there soon and stay in shape.
I'm thrilled for you, girl! Think your development is a lot better than mine, and I'm happy for you!
