This is a painful time for you. I imagine there is guilt and shame and sorrow at losing your friends and social support. Your mom thinks your friends are a bad influence and your friends parents very likely think you are the bad influence. Parents tend to want to blame the other kids!  I have never heard the advice about mixing colors of alcohol being the problem, rather I think you all had too much alcohol and got alcohol poisoning. So my advice is don’t drink. Period – because your brain is developing right now and alcohol and drugs on a developing brain can cause life long issues, including a tendency to addiction. The puking is the body’s way of trying to cleanse the poison out. Your passing out 4-5 times and hallucinating are other signs your body was not processing the drug and the alcohol well. Which scares me for you and I don’t even know you. Although no ones body will allow too much ingestion of these toxins. Drugs and alcohol are toxins. A little bit and maybe one feels good but keep going and one feels bad. Anyway, take this as simply a life lesson. Try to work through this and if you need counseling, please seek it. Consider starting a written journal where you hand write your feelings every evening. Learn to identify what you are thinking and feeling. It may seem trite but this too shall pass. Use it for good. All of us adults have had experiences growing up that were big life lessons. I wish you the best.
