I so understand what you are saying and where you are coming from.
That feeling of validation in IC is so, so sweet. I will never forget the feeling I had the first time I saw a good IC who said about a past relationship with a suicidal ex: 'That must have been really hard.' Those little affirmations somehow give us permission to acknowledge the weight and put it down. I'm glad you're moving toward a healthier place with your relationship to your mom because of it!!
