That's an interesting experience. Reading what you said, I wonder if it's less about the trust issue and more about re-experiencing the bad feelings and loss of control from your days of using/drinking. I had a similar experience recently that really upset me. We had been out late at a Christmas party and I had a lot of trouble getting to sleep when we got home. I finally settled down around 4 am. My husband had to be up at 6:30am for work. I woke up, looked at the clock and it said 9:38. I couldn't believe it, jumped out of bed and ran to check another clock which said the same thing. I ran back to the bedroom ready to tell my husband the alarm hadn't gone off and he was really late and the bed was empty. He had gotten up and left on time and I had not noticed at all. This never happens to me, I'm a super light sleeper, any noise wakes me up and I never oversleep. Well, it really shook me up and I realized it was because it made me feel the way I used to feel when I woke up after drinking feeling so disoriented. It was an awful feeling. Maybe that's what was happening to you. You weren't being accused of anything at all, but the experience brought back the memories of times you'd like to keep in the past. After all, your mother did trust you!
