I can't really add to any of the advice given here but I can say I know exactly how you feel. I am currently in my second break from trading, luckily i've only lost £1300 of my own money (4-5k if you include what i've won then lost) but it can seem as though you're fighting a losing battle.
I don't know you from adam but I am certain your problem is the same as mine: lack of discipline. Even with a solid strategy that I had paper traded successfully for months I still deviated away from it and screwed up.
My only advice is take a good step back from trading, don't even think about it for a couple of weeks then come back refreshed and find a direction you want to go in. Sort out a strategy and paper/demo trade it to ensure it works at least in theory and then get back to trading the smallest stakes you can with a set stoploss % on each trade. I am sure you will come good in the end, just the same as i am sure i will.
