OK, i dont know if its stress (highly doubt it) or whatever but lately i cant switch my mind off, i mean at all, i find myself thinking about the most irrelevant things whenever im alone due to this i can hardly sleep anymore, i just lay there thinking about maybe random stuff and when i've finished with that theres something else that takes me about an hour to get out of my head, i swear i havent had a decent nights sleep in months just because my mind keeps asking pointless questions, and then i have to question the reason behind those questions and so on, please help!
