Tl;dr: I'm a depressed person that's been addicted to benzodiazepines and opioids for 13+ years, and did Methamphetamine when I was 12-13 with my mom. It's probably just a mess of words that don't make a full story. Warning in advance.
I became a daily user when I was 15 in high school. Currently 28 right now, have had less than 10 days off benzodiazepines since then, from running out/trying to quit. And probably about a year and a bit off opioids.
But my first encounter with drugs was when I was either 12 or 13, was Methamphetamine that I did with my mum thinking it would make us "bond" wasn't a good decision. This might be a bit of a read, apologies in advance, if it goes on too long I'll put a tl;dr at the top.
But I started in high school with just Vicodin, it made me not care, so I kept buying/stealing it every day, when that supply ran out, I went to Oxycodone, then when that ran out I went to Hydromorphone or Heroin and Alprazolam. I dropped out when I was in my second semester of sophomore year. (So 10th grade) I also started to get into cocaine near the very end of me dropping out. Which well, cocaine for me is horrible since I have an enlarged heart and multiple other heart problems that I can't spell. So I dropped out, my grandparents let me stay with them off and on until I was 18, and during this time I was doing pretty much every drug that came my way. MDMA/MDA/LSD/etc. Skipped completely out of the Cannabis phase. (Have smoked cigarettes since I started using Vicodin) So 13 years of smoking cigarettes and benzodiazepines.
I think the main reason I kept taking drugs in general is because I never really had someone... to tell me that was a bad thing to do. They did with cigarettes, yet not with the others, since I hid that use from them up until about 2 years ago. Well, back to being 18, I lived with my great friend Jon who was a few years older than me, and sadly died saving my life (I won't get into that story) and he introduced me into The Psychedelic Scene, the Research Chemical Scene, The Darknet Market Scene..., and he was pretty much my life (Note: Not gay, and not going into the horrible story that happened two years ago with my "almost" fiance; mostly it is way too long of a story, just like this.) until he died. I slowly got deeper and deeper into addiction after his death, to the point that my sister had to live with me at my apartment so I could well live there.
Currently I'm still taking benzodiazepines (Mostly Clonazolam) and Opioids (Mostly Methadone/Oxycodone/Hydromorphone/or the Fentanyl analogues) living back at the place I lived when I was 16 with my grandparents taking care of them. No longer stealing their pills or anything. But quitting after 13+ years of Benzodiazepine abuse... is near impossible without going into a long term rehabilitation place. Which I don't have the money for, and no way I could pay for it even if I paid the minimum every month. I've tried it with 500x 10mg Diazepam pills (While taking ~=20mg's Diazepam/day) and I couldn't do it. So... I honestly don't think I'll ever get off of them. Opioids, I've got off of them... probably 100 times (Either from not being able to find anything/or wanting to quit) So at nearly any point I /could/ get off of them, but what's the point really now? One of the safest classes of drugs, when not used in tandem with other depressants. Which I only do every day. One day I'd like to read back on this clean and tell myself "I fucking did it" but I don't see that happening ever.
Just read the OP... I started because of well I was bullied in school, because I was the depressed 55kg teenager that had way too many problems with self esteem and depression that weren't noticed until I was much older in life. PTSD/SAD/just fill in the blanks really at this point.
And sadly since I live in such a conservative place, even if I do break (True story) my fucking growth plate in my hand, and got told by the doctor honest quote "I have bad news for you, your growth plate is broken in your hand, and since you have a previous issue with substance abuse that were depressants, I can't give you any narcotics, I apologize, but it's against our policy" (I had been in rehab three time; twice before I was 18 and once when I was 23 (That lasted three days) so I had to cold cop, /that/ night with this flimsy thing wrapped around my arm, as I couldn't get any of my regular dealers, and paid I believe 120$ for 15, 10mg Percocets. Which well lasted... that night.
I've had amazing experiences, I've had PCPy/TCB-2/PCE/PCP/3-HO-PCX's/Methaqualone/Aleph-2 (That TR is on here)/etc. I've had some /fantastic/ times in my life, and I've had some days where I've wanted to kill myself. But making that magical number (see below) go higher and higher is sadly what is keeping me alive, and knowing how many people I would hurt if I did end up killing myself/overdosing.
I've taken #337 different drugs, either illicit or prescription drug... honestly my life goal is to hit 400 before I die. Which well, I have the psychedelics/stimulants/empathogens here to do it, but I still haven't even had DMT yet.
