Got a problem that needs to be fixed immediately!

Just got demoted to Silver IV because I lost too many games. The cause of these losses is my bad habit of playing too aggressive early game or playing too aggressive when i'm behind. I played Starcraft 2 heavily before I started league, and tbh it's fucked me. When you're behind in SC2, you have to play aggressive, or you lose bc the opponent will get ahead and crush you. So I automatically start to push when I should be farming and feed more...I can't get rid of this habit, it's hardwired into my brain. Any suggestions to help me rid myself of this terrible habit?
