guilt
Don't people have an uncanny knack of making you feel extreme guilt over things that you really shouldn't at times? You can work so hard at something, ploughing ahead day after day and then when you eventually get there, it somehow feels as though the whole thing is suddenly a burden to people.
Sometimes keeping up your side of a deal just doesnt seem to be enough, not when your side doesnt consist of money and complications, just because your side was hard work and graft.
I hate that constant feeling in your stomach, a wash of guilt. Even if they dont mean it.
Drink, anyone?
