any thoughts or feelings that come up that I am unworthy of love for any reason I can just choose to love myself no matter what and honestly this tactic could probably calm down my borderline pd trait stuff because a lot of that is rooted in fear of abandonment and rejection and not being loved enough
It to me sounds like overcompensating, bringing about a different problem as a direct reflection of the first one. They are both just as extreme as the other and root from the same place.
The healthier idea would be to recognize that, in spite of how you are not unworthy of love and while it is good to have self respect... that the problem is closer to your extreme fixation on the concept itself. Your insistence over "good things" becomes a bad thing through how much you overdo it, and in that action you end up pushing people away as their response to your acting out reinforces your insecurity.
I treat it like managing emotional blood sugar levels in that having it go too high can make it bottom out and crash, while manageable amounts by contrast can be healthy.
My advice: Chill out about needing to feel loved and it will come on it's own slowly, and that the midground of love and hate is contentment.
