Weed screwed me up

So I think I have been having delusions of some kind while being high off marijuana. I used to smoke every day for about two weeks and never had these delusions.Eventually began smoking more and at one point everyday . Then one day i seemed to snap. I smoked and my body was shaking. From now on I have felt like everyone is laughing and talking about me. I almost have anxiety attacks. I been feeling lately that everyone thinks I'm terrible and that nobody wants to hurt my feelings cause it would cause me too kill myself or some bullshits. I didn't Trust what anyone says ,for i believe that whatever they say they think the opposite and they're trying to get my slip up so they can laugh at me That's when i'm sober. When I'm i high i feel like I'm gay and just laughing at me and making me do stupid ****. I analyze my every move i make and then relate it to how it makes me homosexual. I tend to make weird gestures even though the gesture doesn't reflect how I'm thinking but it comes off a different way i think. I have no idea what do i know its kinda of choppy but any help would be greatly appreciated. I've been like this for a month now eventhough I stopped smoking. When I'm around people I get very nervous and sweat a lot, i feel like everyone is watching how weird I am. please help me.
