I wasn't able to stop on my own, let alone control any aspect of my own addiction. I always went back to my old ways which is the natural, chronic progression of the disease of addiction.
Have you ever sought therapy or counseling before for this? Depending on the treatment plan that is discussed with you, detox may or may not be suggested as a first try. You can request it. Then decide what insurance will cover it.
A case has to made for your admission into detox and/or inpatient treatment. It can be like jumping through hoops at times and can be frustrating.
The insurance may initially deny an admission and the counselor will have to re-apply for you. They know some tricks and which insurance may be easier to apply for and get through than others.
Waiting times vary. A bed may be available right away. Be prepared for immediate admission. Any hesitation and the bed won't wait for you. They have to see a strong interest and commitment on your part for recovery or they may not go to bat for you.
Less expensive outpatient or group therapy may be suggested first. No insurance is necessary for NA (narcotics anonymous) and it is free.
A DID diagnosis may get you a 'dual diagnosis' label. I was a dual-diagnosis patient. It was very frightening as they were telling me that my chances at recovery was less-than-average. I did make it however. It is one day at a time. I had to be drug/alcohol-free before any other psych treatment would work.
Listen to their suggestions. Consider your best treatment plan option and follow through with it.
Recovery is always worthwhile. Best of luck to you.
