You are very lucky to get so much attention from 25, she is amazing and did it all.
She is giving you very good advice, she made the mistakes we all do when we start on this road and she made it right for herself.
So, I can say I am very proud of you... for listening to people that have been there, for trying hard to follow some of the advices the vets are giving you, and follow some you are learning on the DB books.
No one here will ever say that you just do it. Everyone here knows how hard it is, how painful it is to go through the S, D, dealing with kids and all our emotional turmoil.
But one thing you will always hear... the encouragement to become a better person with or without your H, to improve yourself, to treat yourself with gentleness and respect.
It seems you are doing it already. Don't worry if you have good days and everything you planned happen and then you have a bad day and it feels you went backwards. Don't punish yourself, it is just normal. It's time that make it easier, it's time that gives you new perspectives, it's time that makes you see the situation a little more clear.
Keep posting... sharing is a powerful weapon against feeling defeated, hopeless. We will always help each other.
