Here is yet another video that talks about breaking down and hitting a wall and taking some time to allow yourself to take an inventory of the positive energy you did put out there. You did achieve things, you wanted to give in a positive way and you did. The problem was that you genuinely did not get true positive back when you should have.
I know for myself, I definitely hit one huge wall and I am still suffering from a very toxic person and I still have things left in what I am going through where I have to deal with this toxic presence a bit longer. When dealing with a narcissist, they just create truely "fowl" things before you can finally end whatever you need to end with them. It's pretty bad when having to learn how to just do your best with how truely fowl ending something with a narcissist can be. It can leave anyone very drained and deeply depressed.
So here are some words of wisdom from this woman that may help you some. Truth be told, I myself have hit a wall, so I feel for you and I myself am listening to this advise.
