I smoked a good strain of weed and had a bad panic attack, i still feel wierd 3 days later, whats wrong with me, will it go away?

Marijuana effects: I understand your distress of panic attack. If you have not had panic attacks before this episode; not using Cocaine, Amphetamines or Alcohol; not going through stresses with unresolved feelings of anxiety, fear, hurt, guilt, resentment-feeling weird will decrease in next few days.
