Who made the decision to put her in long term care? Just curious because it might have something to do with your feelings. Not saying it wasn't the right decision.
As to your thinking you might relapse, that is your AV talking to you. No reason at all after two months that you can't be sober, and in fact you will be more "present" to deal with things and for your mom.
Congrats on two months. You are free for life if you want.
