This is going to sound harsh but it is the best advice you will ever receive. Your method of doing form makes absolutely no sense and it will not be successful in the long term. I understand you had a big win once but it was pure luck (similar to a jackpot win on the pokies). For the sake of your family and your health, please consider lowering your stakes significantly or stop betting completely. You are (possibly) currently ahead of the bookies and the only way you will stay there is by stopping now. You will not win more by using this method.
