...it's making me feel like doing SH

Ok, so everyone here probably knows I am struggling with obsessing over ex T. I want to stop googling and checking her FB, I really do. It's getting out of hand and having a really bad effect on my mental health. It's making me feel on edge wondering what next piece of unwanted info I am about to learn, it's taking up time and brain space when I could be doing and thinking of something else, it's stopping me moving on with my life and most of all, I HATE MYSELF FOR IT! After each time I check up on T, I am wrecked with guilt and feel like I need to SH as some kind of cleansing/punishing ritual. It's like binge eating and then feeling disgusted with yourself so you force yourself to be sick to put things right. I have managed to refrain so far but I really need to stop googling and would really appreciate some advise on breaking this habit, thanks.
