I've gotten some very solid, very heartfelt advice from many friends. It seems the ups and downs I've been feeling are common. I've decided that one to two weeks off of the structured training (Ex suggested that a week ago) and some easy rides, along with some girls night out time is in order. It's a matter of learning how to cope with this 'all in or nothing' sport we're all in. As I said, the physical is one thing. I undersold the mental toll!
From those of you here who have offered advice and help, I am so grateful. OMG, I wish I could hug you all!
