It's great to have an educational goal, but I strongly recommend getting off drugs first. And I'm not trying to be insensitive, but what's going to prevent you from going on another RC benzo bender? What's changed, what are you going to do differently?
I agree with this. CJ It is great to have goals for education, a job, and moving, but focus on yourself and get completely sober before you go back to university or move to a new area of the country or another state. Drugs, dealers, and people that use drugs are going to be anywhere that you move to, and you have to realize you cannot use them.
Otherwise nothing is going to stop you from relapsing, or getting addicted to other drugs in a new state or new area, like you've had happen now with coke. Stay far away from that dealer.
What is stopping you from going to a hospital or detox place or rehab? Are you afraid of getting sober? Or do you tell yourself that you can get sober on your own? Or do you feel like a failure?
Don't beat yourself up about using coke and other drugs, but see it as a learning experience that tells you that you can't use drugs, and need help to get sober. There's nothing wrong with being an addict, or asking for help to get sober or with going to a hospital, detox, or rehab.
Sometimes for a lot of us addicts it works best to quit drugs in steps, but for other people rehab and detox, and stopping using all drugs with the help of a medical professional are the only options especially with benzos, alcohol, and other drugs.
I remember when you were sober and things were going well, and you can get sober again, but going to a rehab or hospital or detox place is the best and safest option especially with the benzos, and to get away from the dealer and other sources for drugs.
Have you told your parents any of what you wrote here about the PTSD, etc.? Or how you need their support and love?
I hope you have a safe new year's eve, and a wonderful 2017.
