There are many people who have partners, spouses and children that go to rehab.
Every rehab has different rules for phone calls. While I was in medical detox, I couldn't use the phone at all. After I finished with detox, I was allowed to use the phone, with my therapist present, once a week for 15 minutes. The reason for that was so the calls would be productive and encouraging, and if they turned negative, he was the mediator.
After I was there for 20 days, I was allowed to use my cellphone twice a week for one hour. I gave the rehab permission to tell my mother and husband everything that was going on with me whenever they called. My mother called twice a day and my husband once a day.
I understand how you're feeling about it. I felt as though I was leaving everyone behind. I was scared. I didn't know what to expect...the fear of the unknown.
Please don't let this deter you from getting help. Use this opportunity to get well. Everyone who loves and cares for you will be waiting for you with open arms when you get out. You will be so glad you did this.
