Man, look. You're not a child anymore , everyone has suffer , some more then others but that won't matter and change anything.
What is important and will change things is what we do from now on.
I am writing this to help you, not to judge you , as we are spiritual Satanists and we shall stick together.
The thing is you're not a child anymore, you're a grown ass man and you should take charge of your own life now and by that I mean to accept what it is ,not to hide from it using stuff like alcohol and drugs , now I understand that there are times where the desperation is so massive that we used to say "I can do this as I can't take this pain anymore" so we are trying to justify and make the bad things look as good things which in reality we know drugs and alcohol are only shortcuts with worse effects in the long term but you probably discovered this by now on your own skin so stop doing it.
You say is nowhere to go but there's many places/ways to go.
In this regard it could be complete destruction or a new you, a better you , a higher place, a higher you and by this I don't mean stonned.
I do not know nothing about rehab places but I'm sure the meditations and the information's here will help you more then anything else if you truly whish to change and heal, you will find the resources to do so.
MY ADVICE:
I would honestly advice to look into your natal astrology chart, I like what Mr Henu said about "better yourself" but I would advise to "knowing yourself" more then you can start the better yourself. Look into your astrology chart, discover how you work , what's your pro and cons, how do you think the way you think, why things happened , what things will happen from now on? What influences me right now[and before and future] ,how, why so on. Astrology is the best and the most divine thing that will help you , BEST.
I would also advise to get into psychology , start to read books about traumas, how do they work ,how they affected you ,how can you heal from them.
We might say we know who we are and how we work but subconsciously we do not know deep down what actually affect us the most , that's why I want to get more into dream study, at the moment I can't but I am looking forward for that moment , I have trust in myself but mostly in the Gods, you shall have too but then again remember that the Gods themselves want's us to be independent and responsible but when there are things beyond our powers they never fail to surprise me with their kindness , love, tolerance and so much more.
You can also do Father Satan invocation and tell him what you have on your mind and soul, release your emotions and thoughts and be open and free to him , ask him for guidance and help and empowerment.
