League makes me sad

I feel like I am addicted to league of legends because letting myself play one game always turns into hours, leaving me feeling empty and sad. Instead of other things I will just be inside playing it with all my spare time and once I get off and there is nothing to do I fee trapped and on edge. I dont really want to play it for this reason but I always think I can just play it a little which I cant ever. I even cant stop sometimes when I should be sleeping for work which has messed up my job because I will be too tired for work and try to pretend to be sick or just be super out of it at work. I dont think I want to play this game any more at all but I always seem to come back to it. And it feels awkward to play with my roommates listening to me click furiously late at night in the other room...
