i hope you haven't given up yet.
looking at your posts, it seems clear to me. you had a winning,profitable method. you put too much pressure on yourself to get more money and started trading bigger contracts therefore putting more pressure on yourself and making you lose your cool hands. you were doing fine in october. you have what it takes to do this (obviously). just go slower. start back with only one contract until your track record gets going again like in october. once you get back to 90% profitable trades or two weeks straight of profitable trading or some goal like that, then try 2 contracts. if that goes well, try 3. but build up gradually, don't make yourself crazy trying to do it all at once.
i did EXACTLY what you did. my biggest loser day was one in which i was trying to "catch up" for having done poorly earlier on.
i really think you have what it takes. i hope you don't give up.
if you do go into the big rig thing, maybe come back to trading after a break.
as one earlier poster said, i'm sending you the positive vibe....
