Hi Baseball,
It's neat of you to share...that's the first step in dealing with stuff.
Just to recap, to ensure I understand your history correctly...your recent addiction is due originally to a back injury and the resulting pain, and prior to that, back in your youth (I use that term loosely, I am 46! LOL), you had addictions to coke and other substances.
You're now in a job that you're not really excited about, but you have no choice, you have a family to support. If you had your 'druthers (another old expression), you'd be doing something a whole lot more creative, related to music...
There's lots of ways to come off drugs. There's ways to do it easy and there's ways to do it hard.
The bottom line is, if you're still crying inside, and until you resolve that longing within you...the rest is a moot point. You will only pay lipservice to the drug rehab if you don't really feel it inside. There must be something inside you creatively that can get out and be expressed, or you will continue to stifle it with drugs. It puts you in a "lala" land where you don't really care anymore. Being in that "lala" land also squelches any desires you may have had to pursue your dreams. It will get you through today, and make you care less about tomorrow.
I know you want to be the person you just know is inside you screaming to get out and express yourself.
My thoughts and prayers for you during this really rough time. You are a good soul and your family loves you a lot.
Karen
