Kacey2 I am so sorry you are surrounded by such outrageous and extreme unhealthiness.

You are like an oasis in a desert. I'm so glad you choose to go another direction and that you choose to get help with that in therapy. Of course tell your therapist all of this if you can, what it was like for you, how you imagined his holiday and felt jealous. There is nothing wrong with feeling jealous, it's just a feeling and it says something about you that is good: that you want a better life and healthy close fulfilling relationships for yourself.
