I can't get past flatline

I've tried the 90 days challenge 25 times and I've not got past 17 days. At the beginning it was let me just take a peek of a video and then let me just climax and not cum and then accidentally cuming. But now it's that I just get depressed and I feel really lonely and everything in my life isn't the way I want it to be and it all kinda just pushes me to porn to feel the pleasure and fulfill my desire and sort of a stress relief and then regret again. How do i stop loneliness (I don't have money or friends, the best I have is I can play games with some of my game friends in my phone and also there's lockdown) and prevent the depression?
