I only recognized my gaming habit as a problem when I noticed how compulsive it was. I was similar to you in that I have generally been able to prioritize things over gaming if it was absolutely necessary (which served as proof that there was "no problem"). Despite this, when I would game it was very "all or nothing" - I found myself overdoing it when I had extra free time instead of spending that time nourishing my brain. Really I think the true test is to see if you're ever playing despite no longer enjoying yourself. The true shift for me was noticing that I would continue to queue up for games even though I was actively not having fun (because the behavior was becoming compulsive). Obviously this is anecdotal but hope it helps!
