Me and my friends were smoking some weed and drinking a bit when I noticed my heartrate rising (it raised so high I almost fainted and lost track or reality for a couple seconds), this then led to a panic attack and I honesly thought I was having a heart attack or a stroke. I then calmed myself with the help of my friends by taking deep breaths. But the negative thoughts made my heart race again with every negative thought. Its been almost 3 hours and while Im very tired, my heart is still at around 110-20bpm while faling asleep, making it worse. Ive walked a bit and washed my face that helped temporarily, I made sure I wasnt having a stroke by doing tests of it. But its still going on and I was wondering if anyone had any tips to make it better :/ thanks
