Mixed ketamine with a few other substances and now I'm super sick

So I am a fifteen year old boy and very new to ketamine. I don't drink or smoke weed (at least not often) I did a ton of ketamine in one night. 5 bumps. And then the next night, I did some more. 4 bumps. On my final bump of ketamine, I smoked an ungodly amount of weed and did a balloon. Almost immediately I started shaking and spazzing out. All my nerves were on fire. I started rambling and turned super pale and purple. I couldn't understand a lot of what people were saying and started having audio hallucinations. Like I would hear a fan and think it was a man whispering come here. I got really nauseous and could barely walk without falling over. I also could barely see anything, as everything was either super dark or super staticky. The next day, I was twitching and having a hard time walking straight. I kept falling in and out of sleep. That night I sleep 12 hours.

​

It has been 2 days since this incident. I am still twitching randomly and nodding off into sleep even though I am on no drugs, a decent amount of caffeine, and getting a lot of sleep. And now I have a super sore throat, stomach cramps, a headache, and a lack of motor skills. I also feel either super cold or super hot all the time. I am starting to wonder if the ketamine was laced with something else. What do you think is the main cause of this?
