how to stay off my phone?

yeah i'm going blind now and i was doing well keeping to only 3 hours but now i'm even more sad than i usually am. i played a game i downloaded recently to get rid of my sadness and became addicted. please help me, most of my happiness is from the phone but not even that can always keep me happy. other things won't work compared to my phone. i'm too tired to always go out to keep myself happy. the only positive thing is that at least i don't go on mangago 24/7 but now i go on something else 24/7.
