My son entered a one yr. rehab exactly two yrs ago this month.
Same rules as you state, one call ea. Sunday to his parents only. He was not allowed to read books that weren't about recovery, etc.
His focus must be on recovery. If he doesn't get it, everything else in his life will go back to being a disaster. My son struggled a lot the first few months as well.
That is when they really need to dig deep and do the work of recovery with no distractions.
Get busy focusing on something besides him...leave the space for him to get well. His life depends on it.
The rehab knows what they are doing.
What ARE YOU DOING TO MAKE THIS A MEANINGFUL PRODUCTIVE YEAR FOR YOURSELF. WHAT ARE YOU ACCOMPLISHING? This is what will make a difference.
My son went to short term rehabs twice.
It wasn't til he went for long-term at 23 that he got well.
Is his rehab in AZ ?
