Tripping for too long

I went a rave on new years and dropped 1 at 8pm then did another half at 12 , I did coke throughout the rave till 5am and I was still tripping at 10am and it didn’t go away when I got back home on the 1st of jan ,on the 1st at 5pm I was still seeing wavy patterns and everytime I closed my eyes I’d see people talking and have audio hallucinations and it’s scaring me that I was going to be stuck like that I finally went bed at 9pm till 12 on the 2nd the next day and it’s been 2h and a half since I’ve woke up and I can still see light patterns,I think I’ve fucked my brain and I’m really scared because I’ve got to go back to my parents house on the 4th and I just want to cry as it should be over by now I did 2cb like 3weeks ago and did 1nhalf and it lasted like 5h and then I came down and i was okay the next day I was so close to calling a ambulance on the 1st but I didn’t because my parents would never think that I’d do drugs I’m so scared right now and I just want it to be over ,if this has happened to you please let me know how u solved it and if you know how to stop the patterns please give me a message or comment because it’s really starting to send me west Edit : so I got around 2h extra sleep and it has gotten better since I went bed but everything still feels abit off and I think my hppd isn’t making it any better as I can still see the patterns slightly ,I think I’m very susceptible to psychs because one time like 2 years ago a 2cb when it was mixed w md lasted 12hours
