You are a shy person...thats all there is to it...weed makes people chill/calm/not care. whats important is that you dont lose your ability to socialize without weed. Just remember....weed doesnt make you act any certain way...you are always you....feeling disconnected is all in your head stemming from insecurities...you should find atleast 1 friend that you can always be with and feel comfortable around...its always better to have an aliby.
