Help

I keep relapsing and I don’t know what to do. I notice I usually relapse when I am home on my days off. I know I am supposed to find a hobby and keep myself busy, but it is hard. I have a list of things to do, but I start procrastinating. I get very lazy. And when I get lazy I start thinking about lustful things. I know it sounds easier said than done when I shouldn’t be lazy and just keep myself busy, but it’s really a struggle for me. Does anybody have any advice on what to do?
