Need Help Now

Hello, my name is David and I am 17. I started smoking marijuana this month, but last week I smoked a lot and got really high. For a few days, I felt fine, but now, about a week later, I have had constant panic and anxiety for almost an entire day now. My entire body is shaking and I just threw up my dinner. My brain feels like mush and I feel terrible. Please help me. I don't know what to do.
David take a deep breath, take many in fact and try to calm yourself. If those feelings don't go away soon go see your doctor but in the mean time it is a good thing that you came here to ask about what you are experiencing. Not everyone can smoke pot and it seems like it is taking a toll on you, so walk away from smoking it if you can and these bad feelings will not be yours to experience. We are all different and react to drugs differently. Being clear headed is the ideal David as we can then experience the world with full awareness. So happy you sought advice David as it is a true sign of maturity and your parents would be proud, honestly.
