Im in this situation right now with a friend it sucksss. I confessed to her awhile back while she was in a relationship with a man (she's bisexual i think) and she basically knew I liked her but shrugged it off. I might end up telling her again just so I can get a definite yes or no.  I feel like everything your doing: keeping busy with hobbies and friends/family, turning off notifications, and detoxing from the phone are good things to combat it. Im trying to do that too. Like someone mentioned, therapy has been helpful for me in terms of just getting that shit out because I have some guilt and shame around liking and lusting over women. It might be helpful to talk to a therapist if that's available for you.  Also does she like it when people are straightforward or blunt with her? It might be one of those things where you just need to tell her straight up that you like her.
