Quitting daily 3mmc & 2fdck use

While I have done a fair share of all kinds of drugs and gotten into and out of addictions before, I've once again fallen into substance abuse. It began about 2 months ago when I got into a very busy, stressful, exhausting period and started with some 3mmc as a little boost, which of course turned into daily use. After a few weeks, I started dabbling into some 3fdck too, at first only a little, but the past maybe 2 weeks it's been a lot more frequent.

I've already detoxed from heavy 3mmc use before, but I was mostly using it socially, constantly going out, staying up for three days, going to events/markets/shops/whatever doped up as fuck, 'let's just do another line before we go', etc. but that all stopped when some big drama happened in the social group and I quit cold turkey because I was sick of it.

This time tho, it's a bit of a different situation (also with the added 2fdck of course), I've been isolated, using alone, staying indoors, barely seeing anyone or doing anything except working and then just doing chores or games. The past few days it's gotten so bad that I'm almost agoraphobic and every day I plan to go outside to run some very necessary errands, but I just can't do it and stay inside, 'frozen'. I've lost a lot of weight, food tastes like shit anyway, I've always been a bad sleeper but now I can barely sleep at all anymore, I've missed/cancelled appointments, didn't even celebrate my own birthday, barely reply to anyone, I haven't done the laundry in weeks, etc. I've neglected myself, my family, friends, house, body, .. and it wasn't even fun. At least before, I was having fun, I was getting something out of it, but now I just feel bad. Mentally and physically. I sometimes dry heave before my first line of the day. I do my line and feel okay enough to kind of function, but I don't get any extra positives out of it. Sometimes I do lines and still just stay stuck in bed.

Anyway, the work project which pushed me into using more and more is almost finished so it really is time to quit now. I had a terrible night again last night, woke up with a migraine and felt shit because of all that anyway, so I decided today was a lost day and stayed in bed all day, but I've also stayed sober. Last lines were probably yesterday evening around 9-10 pm. Normally I'd do a first line around 11 am - 1 pm. It's now 9 pm, so I've been 'sober' for about a day.

I've been eating little bits and hydrating. I was sort of okay during the day (rewatched the Dune movies, so lots of action and immersion going on to keep me distracted), but now I'm starting to feel shitty and the cravings are here. I KNOW doing a line now doesn't make any sense bc I wouldn't enjoy it, it wouldn't be productive and I should just try to go to sleep soon, hopefully get a better sleep tonight and tomorrow will be another new day but it's still hard.

I don't know what I want to achieve with this post, I guess I just wanted to get it of my chest as nobody knows how bad I've been doing because it's been a very 'private addiction' this time. I know I'm strong enough to quit it (I've quit worse stuff before too) and I'll start feeling slightly better in a few days but yeah.. I'm lucky that I at least work from home and for myself, I have a lot of freedom, no real constraints, enough money and comfort and time.

I've read a few other similar threads, but any other tips for recovery etc. are welcome, especially specifically for the 3mmc+2fdck combo.
