Is it normal to feel this way after five days?

A week ago, I smoked a joint with my friends -a small group- and I also smoked the day before that with a larger group. The day I smoked with the smaller group, I felt it instantly and I had a tunnel effect, which I expected. However, soon, my heart rate increased drastically and I thought it would go away by the time I got inside, but it didn't. I sat down and I tried to calm down, but I just began getting very hot and tense and everything in my body felt amplified. I went to bed thinking I can go to sleep instantly, however, I began getting very sick and feeling I'd throw up. Small things like gas to burp or fart felt like pain and was amplified. I was panicking like crazy because my heart was beat so fast for what I believe was three hours, and what was even worse was it felt amplified so it felt almost like four beats at a time. Everything felt slow, almost like a dream like feeling, and this wave of heat was over me and subtle numbness. I was able to breathe normally, but even after I was able to not think about it as much, my heart was racing and I was shaking/shivering with fear. After a while my side started to hurt, almost right under my rib, and those small muscle spasms you have before you go to sleep would cause my arm or leg to shake hard but not more than a few seconds. Every time I was able to fall asleep, I had a feeling like I was being dragged down as if I was melting, or a better example, that force your body feels on your face on a roller coaster causing you to be pushed against your seat, I thought I was going to die because of how fast my heart was beating. After I finally fell asleep, I obviously had a very subtle chest pain due to overworked muscles, but on the second day I was fine. Four to five days later, I had an episode where I was thinking about something and I went blank i couldn't remember what I was thinking about/saying for a moment and I felt a wave of numbness and a hot flash come over me and I was panicking that that night was happening again, someone in the family checked my heart rate and blood pressure and it was somewhat high, I was shaking from fear after the episode ended ( it lasted a minute) and my face was red till I went to sleep. The next day I was eating and it happened again but barely lasted thirty seconds. I went to the ER that night and they said I might be having panic attacks (they don't know about the weed). Currently, I still feel a bit paranoid, my vision is fuzzy, but it's so subtle it's barely noticeable, I feel a little hazy as if I'm still in the dream state but subtle as well, and I'm not sure but I don't know if I can really feel emotions. I feel like they might be a bit numb. I feel as if a lot of things are numb (feelings, touch, sight) I can feel pain normally, if I take my nails and scratch myself a bit or just touch my leg or something. So, I feel as if it might be nothing.. But I want to hear from anyone that has felt this and overcame it or an expert with marijuana. Thank you ☺️
