It is awesome that you have wonderful resources at the ready and that you didn't lapse into old patterns.
I would share that with my family (mother and sister), I flat out had to turn my back and not respond in any way to voicemail or email or old fashioned mail. No telling them about boundaries anymore, just living behind the boundary that I set, giving them nothing. Unfortunately, due to my mother's Alzheimer's diagnosis, the boundaries have been breached over and again over the past 4 years. With my mother, I have ceased calling her because she has been at the point of a raving maniac since last October due to her disease. I chose, however, to be her POA last year, so I manage all aspects of her life. It's very triggering to have her front and center in my life when she, for all intents and purposes, destroyed mine. I'm having to redefine boundaries in managing her care within myself so that I take care of myself. I'm inspired by your ability to not go the way of maladaptive coping. I'm working on that. Wicked difficult for an ACOA who has addiction issues! With my sister, the email and conniving have stepped up due to my mother's illness as she wants her money, but after the last slanderous email hit my IN box, I made a decision that the next time one comes my way, I will be forwarding it to the attorney and asking that she take some kind of action to shut my sister down. That's my boundary with her. She gets no more of my time, attention, or power. Nada, zip!
I guess this is all to say that sometimes boundaries have to flex, but it sounds like you need space and time to deal with your needs right now. Your parents don't make this decision, you do. They don't have a vote in this matter, this is your life. Now, you just have to enforce it. Perhaps, you need to turn a deaf ear, as I did, and not respond to them, period, until you are ready. VB
