Yes, I know those feelings to a certain extent, as well Crypts_Of_The_Mind - I really do.
For me, it's like I can see the tunnel and I can see the proverbial light at the end of the tunnel, but it never gets closer - in fact it's getting further away just like in a bad dream.
Anyway, you're not alone and tomorrow will be another day. Perhaps you'll be feeling a bit more optimistic too.
