What the **** is wrong with me?

I have a lot of friends very nice family but I am always on a bad mood if I am not high, I am not addicted but I like to smoke some weed, I didnt smoke about 3 month cuz in my country there is no weed in summer, and I swear other drugs are just a dream, but the question is why I feel so uncomfortable everyday I had GF we broke our relationship but I dont care I ll have another one if I want but I dont want, I dont want anything wtf. I am not stressed and I have no depression. I am really smart guy but its just a game I am fu**ing sad inside
