You mention smoking too, I'm assuming it was marijuana or some synthetic equivalent? Since you say you did not drink a lot and this does not sound like you I'm wondering if it was the smoking? I can't smoke pot, wish I could because it seems to be very pleasing for every one I know, but it has a negative effect on me. I get really paranoid and anxiety attacks. I'm not talking paranoid like are they talking about me stuff, I'm talking I know they want to kill me stuff. So I can't smoke at all. I'm wondering if marijuana could have other effects on other people? Not trying to excuse your actions, just wondering. I would talk to some one about it tho.
