I know exactly what you mean Jean. I've felt like you do many, many times but I still stick at it because I do enjoy it most of the time.
Chatting on these forums is not the same as face-to-face conversation so I have a suggestion. Why don't you see if you can get a temporary part time job? That way you can still enjoy the thrill of your eBid shops and selling but also have the enjoyment of a routine part time job. If after a few months you decide that you prefer to be a full time eBidder then at least you haven't shut shop so to speak.
