You need support, you need to consult your doctor. You can't use your diabetes as your clutch, instead consult a doctor and make sure that your okay. I don't know how drug abuse and diabetes are related, I just know it sounds like you are getting closer to quitting, just not ready to take that leap.
yes, I have a job. I am a teacher. Last year when I quit I was teaching kindergarten. I have a family, it was complete hell. I never ever want to go through that time again. I was laying in bed, sick, didn't want to see the sun, could hear my daughter out playing while her mom was in bed sick due to her own abuse. It was awful. Now I am 8 months clean, feel better than ever. It is a challenge, but you have to want it bad enough. The addict in us will make every excuse to hold onto the drugs, its amazing how drugs get a hold of us and make us into people we would despise if we knew on the outside.
You can DO THIS I HAVE ALL FAITH. Do not do it alone though!
