I'm sorry your going through this. But if i took one thing away from your post, its that your an amazingly strong person, and if you can hold a job while still being addicted, you can do just about anything you put your mind to. Your still young and have a lot if living left, dont give up hope just yet. I know you probably dont want to hear this, but when your ready to quit (which it kinda sounds like your at that point) you got to force yourself to get help. Maybe tell your dad that you relapsed (but spare him all the gory details u told us tho, atleast that's what I would do lol.) I know what it's like to be that depressed, and how hard it is to ask for help. But you can still have everything you want out of life, you just got to be willing to fight for it. I dont want to come across as a hippocrate, i have enough problems of my own. All I'm saying is I know how hard the struggle is, and I understand how difficult it is to break out of that habit and ask for help. But maybe your dad can help you find some sort of temporary rehab, just till it all gets out of your body. I dont know what type of financial situation your in, but A.A./N.A is free and I can tell you from first hand experience that there are people who are willing to invest their lives into helping you stay clean, and it will create a better environment than being home all day by yourself. Also, maybe you'll be able to find some good friends who truly care for your well being. Who knows, maybe you'll even find your true love in those walls, after you've been sober for long enough. I never like to step into other peoples buisness and I never judge anybody for the path they decide to take, what doesn't kill you makes you stronger. But you sound like youve hit rock bottom, so maybe its time for a change. I'm sure I'm not telling you anything you havnt heard b4, but hopefully I can give you some encouragment that your life is not over. You're just gunna have to fight for what you want. After everything you've told us about what you've been through, I have no doubt in my mind that your strong enough to work past this small bump in the road that you've hit. Remember it's never gunna be easy to ask for help, and your rock bottom will always have a trap door to it. But I can promise you, if you work hard enough, you can have the life you've been dreaming of. Oh, and as drained of dopamine you feel like right now, your brain will repair itself. Kick the habit, and with enough time your brain will go back to it's normal functioning. Good luck! I know your more than capable of handling yourself. You're a strong person who deserves better, so give yourself a chance to have that better option.
