I am so lucky I never OD'd. I was taking opiates, xanax, adderoll, antivan, meth, coke, K, you name it. It wasn't that I wanted to die, I would just get to a point where I couldn't remember what I took or how much I took. There is a big difference between accidental OD and suicide. One of my best friends was drunk as hell blood alcohol level was 4 times the legal limit by the time I took her to the hospital, because someone gave her some methadone. She had no idea what she was doing. She was basically a drinker, never really did anything other than MDMA. I had no idea how much she had drank or that she took the methadone. Everyone left and she was passed out snoring realling loud, so I just covered her with a blanket and went about my business. A little bit later she wasn't snoring but was breathing, I touched her and she was ice cold.
I was freaking out. The house was full of drugs. I didn't know how many she took, how much she drank. So, finally my bf at the time and a friend helped put her in the car and I drove her to the ER. As soon as they got her out of my car I heard code blue in ER. I freaked out. They interviewed me I told them all the drugs I had because of my medical issues and that there was a girl there with methadone. Toxicology screen came back negative, so ahe had only drank and took the methadone. They told me ther core body temp when I brought her in was like 80-85 degrees which is hypothermic. She was on a ventilator. And I had no idea what was going on.
I had to call her mom, and she thought that she tried to kill herself and I assured her that was not the case. That it was something we had discussed and she said she would never kill herself because she loved her mom too much. The fucked up part is that they blamed it all on me. Which was sorta shitty, cuz I was at work and walked into this party going on. I ended up having to leave because her family no matter what she told them would not let me off the hook.
Well, years later because she never seeked any sort of help after this happened, she is having seizures, what she calls mind freezes (when her mind goes absolutely blank), she has gaps in her memory, extremely depressed, full of anxiety, and has problems sleeping.
So the point of the story is, what happened to you was an accident but see it as gift. To get not only the rehab you need inorder to function ie. walk and talk but to get the emotionally help you need for your depression, loneliness and you probably have alot of anxiety. Take this opportunity to become wise beyond your years, you are only 18 years old. At that age our friends are usually what defines us. Use this time to learn the fabulous world of self acceptance and self love. So, when you are better and you start seeking new people to be in your life you bring positive people and healthy (emotionaly) people in your life. This may sound a bit harsh, but if there was a time to lose your friend this is it, since you have the resources available to you to help you get through it.
NEVER feel like you have to go through life alone, we weren't ever meant to. Don't give up now, consider this to be the second chance not many people get.
