I am an avid gamer, have been my whole life. I am currently 16. The problem I have is; I can’t concentrate unless I do one thing, that one thing is pulling my T-shirt over my face and biting/sucking on it. Seems childish, I know. I have been to the opticians multiple times and they gave me glasses which honestly don’t help. I can’t focus on anything anymore and it’s really messing with my life, not just gaming. Please, someone help me..
