I quite often feel that way too. But then when I read the ones that actually made it, I also see that the LBS there was feeling the same way.
The truth is that all sitches are like Edz says, it can change very drastically and very fast.
I guess we are doing what we can at the moment, as time goes by we will feel less and less the sharp pain. It will always be there, but will get easier.
Who knows, maybe one day we will all be happy talking about our new adventures.
Keep the good work Toots. It is not easy but you are doing an amazing work to make your life better.
