i think i can do this

i have tried to quit a few times and the most i ever get is 3-4 days and i keep repeating that cycle, i quit feel amazing for a couple of days then i get very depressed and down and end up relapsing and feel terrible, this time i stopped and took a moment to see why i felt like that and what caused it and i feel more confident now that i understand it and know how to beat this, this app and community also helps me a lot so thanks a lot guys keep staying strong and showing support
