i feel your pain man, i really do...
a month ago i was in the worst withdrawal of my life, freaking out, calling everyone i could begging for help .. i just wanted to be put on suboxone offically or methadone , and see a doctor who actually cared about my wellbeing.... It was like no one and no place wanted to deal with me, especially if i had no cash money. Eventually i got admitted to a methadone clinic near my house, and the doctor there is great, but after seeing al the people who go there and talking with them (basically they are mostly the scum of the earth , downtrodden junkies, bottom feeders, and i guess i am too for that matter) i've decided to be cautious about not getting myself more physically dependent in the long run , because methadone is basically free and its so easily attainable, and easy to get your dose higher and higher. Other patients there have warned me, "it gets in your bones and makes you miserable"...... "your withdrawals will last 8 weeks and they are worse than heroin" .... some of the guys there tell me they wish they would have used suboxone if they could afford it.... Other people have told me that with a habit at my level , quiting heroin cold turkey would be better than using methadone....but for me its turning out well, i have never gone about 50 mgs in the two weeks i've been taking it, and the counseling sessions really have helped me out. I also go to AA/NA meetings once a week or so, but when i feel i need the extra support i'll go every day, multiple times if needed, and this is the best thing you could start doing.... yes it sounds like you need more intensive rehab , but sometimes you gotta make due with whatever resources are available... I am impressed with the quality of care and guidance i've gotten from the methadone clinic and AA meetings around town.... Its like the amount of love , healing and "energy" you put into the meetings- is what you get back out of them.... You can bear your soul to the group, and just tell it how it is and what you've been going through and the feelings that are driving you crazy, and they totally accept you and embrace you... and understand you.
So go ahead and do this, find out where you're nearest methadone maintenance and bupe clinic is. My first appointment and dose and everything without insurance or anything was $12, and I was there for like 4-5 hours and saw two counselors and a doctor and had blood taken and tested for TB, aids, hep c, ... I had a rigorous and effective physical, and the treatment was surprisingly excellent. Based on what you've told me , you would benefit greatly from that sort of treatment. Even though they only give you 40 mgs of methadone your first day, you will probably get tremendous relief even from that small dose. Here in california medi cal will pay for basically anyones methadone, and i'm waiting for mine to be approved.
Then look up where there are 12-step meetings taking place around your county, don't worry to much about whether they are for alcoholics or narcotics, cause its the SAME DAMN THING- and the process is identical.... some groups may get bitchy if its all drinkers and you are the only junky - but that is super rare. Usually in my experience they just want you to say "Hi i'm so and so and I'm an alcoholic" -- even if you are actually a junky , its basically branding thing , its stupid... but in reality it makes sense, because you get some dumb young kids who are like "Im brandon , i'm a speed addict and sometime junky , i also eat cheeseburgers etc etc etc" and its not really important in the long run exactly what you were using or how much or whatever... its more about the changes taking place on a deep emotional / spiritual level.... your story would resonate and people would be more than happy to help you on journey to recovery.....
Got to many many meetings until you find the ones that seem to feel like "home" for your recovery..... and then keep attending, multiple meetings a day if necessary.... also apply for state support to get yourself and family financially covered while you recover.
good luck , god bless, i gotta good feeling about you man! Save your family, its all we have in the end!
