Still feeling effects 2 days after smoking

Hello. I am a completely normal guy. I work out and play sports regularly and I smoke weed every once and a while. I can easily go three weeks to a month without smoking. I smoked last Sunday night out of a very expensive bong. The guys I was with said it was worth 500 dollars. Anyways, I took two hits back to back and I was the highest I have ever been. It hit me immediately and I was tripping out. I had never used a bong before so that might have been part of the reason it was hitting me so hard. I started freaking out and left the house immediately and got in my car. I could barely walk, so driving was very difficult. I somehow got to the parking lot of a gym close to my house and my girlfriend picked me up. After getting home that night I had no trouble falling asleep but the next morning I woke up in a daze. It has carried over into the next day where I am right now. I feel out of it and am having some memory problems and just don't feel myself. Doing normal things and talking to people I usually talk to feels weird. I've read many posts similar to this and am hoping it will go away, but I'm scared. I don't like feeling like this. Any help or advice will be greatly appreciated.
