Hi Monica! I've been here a few years ago! Win £5000 on Multiplayer Avalon and reversed £4000 in £500 increments. Biggest mistake I've ever made since I started playing but boy did I learn by it and 5 years down the line I don't think I've ever reversed another withdrawal since.
Unfortunately, there are very few words of comfort in this situation because nothing will ease how gutted you are feeling. I've never been as lucky as I was then to this very day but I have had plenty of nice withdrawals along the way. So if you do carry on playing just remember how bad you feel now now if you ever go to reverse again and that should stop you.
