Laura,
What everyone has told you is right. This is an interesting and strange process we go through when we got sober. I've been sober awhile now and I still find myself stopping short sometimes because I'm no longer the person I thought I was. In a sense, I'm still getting used to living with parts of myself that I didn't know were there. So, I would say you're doing just fine and the confusion you're feeling is just part of the process.
Love, Anna
