What do I do

Guys I’m so depressed I need to loose weight ASAP ! I’ve gained 20 kilos and I’m now obese when I walk I have NO confidence anymore and I’m so ashamed. My issue is everynight when I finish work I smoke weed and binge eat .. I will eat and eat and eat hek my weight gain ..

I can’t stop smoking weed I love it so much .. how can I help my binge eating habit as I exercise 4 times a week but the binge eating is throwing me off ! Please any tips
