Do you keep a spreadsheet of all your bets David?
I never did but honestly,since I have,it has helped me identify some of my weak points. I noticed I was doing a lot of stupid bets, e.g - player to score and respective team to win double. These nearly all lost simply because they looked too good and seemed sound at the time of placing the bet.They had no value and basically reeled me in.(A lot came from "special offer" emails from the betting sites)
However all the bets that I spent a lot of research into had much better success.
After 20 bets or so you can really see certain things that you would never notice otherwise.
I do think you're batshit crazy for betting the amounts you do,it seems you have no bankroll management?
It's never good to see people lose money,especially to the vultures that are bookmakers.
Personally I would paper trade between now and the end of the season,track bets that you would genuinely put money on.
Sort your self out man and stop betting amounts you can't afford to lose.
