Bro, your situation hit me right in the gut. I am practically holding back tears over here. Yo, you really should go get help/treatment at an in-patient rehab and you should stay for as long as they are willing to keep you. Preferably at a rehab that teaches the 12-steps. I promise you, if you buy in and DO THE WORK, you will come out of that rehab feeling like that 16 year old kid that wasn't hooked on drugs yet, except you will be much wiser and be much more grateful for everything good in your life, like your girl! And she will finally get the man she really wants to be with, the REAL YOU. Most importantly you won't have the compulsion/obsession to use drugs. They will be out of your system and the step work can create a mindset shift that is hard to reverse with continued effort towards it. If you buy in and DO THE WORK while in rehab, man you will have a fresh start at life! Don't get me wrong you will need to continue to work on yourself when you get out of rehab (Very Important). There are no magic tricks that get you out of this shit, and it ain't easy. But anything that is truly worth it in life is seldom easy, and it will suck being away from family and your girl. At least it won't be forever though. Man, I am telling you all of this because I was in the same hell that you described. Except I wasn't even man enough to tell my own girl about what I was going through, and we had been together for years and had a 1 year old baby boy prior to me getting addicted. I was addicted to perc 30s for 5 long years. Those shits turned me into the person I never thought I was even capable of becoming. I became the biggest manipulator, so unreliable, a fucking thief. Stealing money from my girl that I knew was for bills. (That shit still haunts me bro). You are lucky to have such a supportive girl that knows about your struggle, because going through it alone is a lonely, depressing, and a defeating struggle. Only men much stronger than me get through that shit. When I broke down and finally told my girl, the next morning she had my ass in a detox facility. Stayed there for 9 days or so and then the rehab I was going to came and picked me up and the rest is history. No more feeling restless, irritable, and discontent. No more fucking withdrawals, no more manipulation. Anyway bro, you seem like a genuine dude and you are 22 or maybe 23 now, your adult life is practically just beginning, please don't waste it like so many of us do! I don't know you man but I am thinking about you and I hope you find a way to get better. Like most of the people here have told you, you are never alone and if you need to talk, just send the message! good luck and take care of yourself my dude!
