Going to detox for alcohol and benzos at the exact same time

Hi. This is gonna be long and complicated. So for anxiety I abused alcohol hard. 10-15 little fireball shooters, PLUS clonazepam 0.5 mg per pill. I’ve been doing the former for 2 yrs same with the latter. On days I would drink, typically I’d go days without taking the latter. Maybe half a pill, 1 pill tops, but typically wouldn’t do the pills for days. I did this interchangeably. Meaning some days I would drink, some days I’d just take the clonazepam. When I would just take the clonazepam without any alcohol I would typically take 2 pills. Maybe 2.5. The last couple of months though, when I would just take the clonazepam, it was closer to 3-3.5. 3.5 being rare, but it’d happen. Oh and was also taking 0.1 mgs of clonidine twice a day. Again when I would drink sometimes it’d be days I wouldn’t take anything, but when I wouldn’t drink, typically it’d just be the regular amount of clonidine, but the last two months or so I’d take 3-4 of that. Does this make sense? Needless to say I’ve put myself into a HUGE mess

Does anybody relate? How are they supposed to treat and detox me from essentially both alcohol and clonazepam addictions going on at the same time, in 7 days no less. I’ve never been more scared or felt more screwed in my life. I’m addicted to two substances that can kill me via withdrawal, and I can’t find even ONE post on the entire internet of someone doing something as dumb as I have. IF there’s someone out there that has, what was your detox like? How did they treat you. I’ve been dead honest with everyone involved, I leave for detox Wednesday morning, and I’m terrified I’m going to like convulse in my sleep, or completely lose lucidness. On top of that currently I’ve been so tied up in all of this I haven’t been sleeping for more than 3-4 hrs a night the last two-three weeks. I’m also terrified it’s going to be unbearable. I have no idea how they’re going to treat this. Please if anybody can relate, and/or provide words of comfort (while being dead honest), please do. I’m such an idiot, and I feel like I’m buried so deep I’ll never burrow out. To the survivors that did, please, what was your detox like? Again, I’m TERRIFIED and I’m STILL doing the above until Wednesday (perhaps stupidly). As I’m scared I’ll perish if I don’t in the meantime.
