Hashish ingested Temporary or Permanante Damage?

Hi everyhone, 6 weeks ago from Now, I ate this Brownie made it with hash oil. One hour later i had a Panic attack, virtigo, i ws really stoned, the day after i was totally out of my mind, i tought that i am living my last days lol, n wondering what's wrong with me, By the Way my Vision became blurred. i tought i am going to be crazy lol,. After one week the things didn't get better so i went to see a doctor, the doc said you fine you have just anxiety, ect...anyhow till now i met 4 doctors and they all say that i am gonna be fine, they don't satisfied at all some of them said that they never seen that.It 's been almost 6 weeks and i still feel weird n a little bit parno, anxious and i think that compard to before my vision has been changed, especially i feel really weid in some public area such mall, stores, crowd.Does Anyone already experience that ? i just wanted to know if these symptoms will go away. i am not a pot or cannbis smoker, i just ingested without knowing this bad side effect.
