Please help!

Hello guys,
I'm 21 years old and I've been fapping since I was like 11. I tried giving up porn many times for the last 6 years failing miserably. I fapped atleast twice a day for the last 6-7years and the best streak I had was of 30 days back when I was 14.
During the pandemic I developed a severe anxiety disorder and now probably depression and the only thing to blame is porn cause I thought deeply about the causes and there's no other possible reasons. I have gone through the website numerous times and tried hundreds of techniques and figured out the best way to deal with the urges is not to fight with the urges head-on cause it will eventually takeover, but by knowing when and how the urges are triggered and avoiding the triggers. This had helped me better than other techniques but even though I know what the triggers are, but I'm not able to avoid them. The trigger I can't avoid almost most of the times and also which kills almost all my streaks is the urges I feel after any meal. After taking any meal I feel lethargic (which is pretty normal) and I can't help myself but to lay on my bed surfing internet(not social media cause I don't have any). Only youtube but just as I go through any triggering thumbnail it's basically over. I've tried doing other stuff after a meal like reading, taking a walk, not taking cold shower because it messes up digestion after meal. Please guys share your thoughts and ways on how you fight when you get urges. It's literally effing up my studies, my career, my life and everything! Help guys!

Also, I'm not religious so please don't share any religious or spiritual things.
