Thanks all, appreciate all your kind words
To be honest I'm probably not at my lowest - that was when we found out. Today was a bad day though and in hindsight posting was probably a bad idea, although as ledkr said, i am quite (too?) honest about how i feel.
Normally, if there is such a thing now, i'm quite positive generally. Like someone else said (sorry, i'm tired and want to go to bed!) i know i have a good life generally, i love my wife and my baby no matter what, i have a good job, nice house and all that crap. I don't want for anything else, except a "normal" baby and normal family life. Nothing's going to change that, but nothing's going to change the way things are.
Riven - you're an inspiration. I hope you don't take this the wrong way, but by the sounds of things you have it even harder than i do. Yes, my dreams are shattered at the moment, but i have a lot to be thankful for and a lot to look forward to. For me i find it hardest when DW (hope i got that right) is having a hard time, she can be very negative about the whole situation, and i know where she's coming from, but it can be depressing. Normally i don't let it get me down, and i am the positive one, but it's hard sometimes.
We absolutely both know we need counselling of some kind, and we'll get it. I'm sure we'll come out the other side better off, it'll just take time i guess.
