First time consuming shrooms

The only drugs I had ever taken before that point was weed which I do maybe 2 to 3 times a week for a year, I've never had anything else, except alcohol if you want to classify it in the same group. So we got to the camp site (it was a trance party out in the woods) and everything was going well, weather was brilliant, company was good and I was in a really good mood looking forward to the nights events. We took a walk and found some people selling shrooms and some really good weed, so we bought both. It was about 7pm and I had a joint to start things off, about 20 min later I ate around 2 grams of shrooms (on a very empty stomach) and sat back waiting for it to kick it, and boy did it. We were at our camp site the whole time and I started feeling really good, the fire we had going started to look amazing, so did the stars. 

Around an hour later the weather turned for the worst and it get extremely cold really quickly, so I decided to go inside the tent for a while and warm up a bit in my sleeping bag, bad move! There was a lot of noise outside from the party about 100 meters away and it started to mess with my mind, all the voices coming from outside was sending my mind into a spin and I couldn't tell where they were coming from. About an hour later it was so bad that it would take me about 15 min to realize that there was someone in the tent with me if anyone came inside. At that point I started to get panic attacks and very bad anxiety which is a first for me, I started wondering if I was going to make it out of the trip or if I was going to die. I kept checking my heart beat 'cause it felt really really low, it was becoming harder and harder to breath as well. I tried my best to snap out of the bad trip, but that is easier said than done when you are in that position.
