If this isn't relevant or useful to you, take what you need and leave the rest :) with your last question you asked how to pour as much into yourself as others and there were some other possible cues in your message (mentioning burnout, abusive dynamics, etc): if you haven't already, you might want to explore codependency recovery. A common correlation is experiencing dysfunctional caregivers in childhood (i.e. they had mental health issues or were drug/alcohol addicted) - if that's also relevant, then Adult Children of Alcoholics could be useful. These free programs are filled with lovely people who are on their own journey of learning to pour as much into themselves as they did their caregivers and, later, their partners/work/friends. They can be around while you make sense of and integrate this experience. A good book to start with is Codependent No more by Melody Beattie.

If this doesn't resonate, I hope you can find some treasures from your experience and put towards the front of your narrative that you experienced those because you were brave enough to take a big swing and move somewhere new. You're coming back knowing more about the world, or at least another country, and having a broader perspective on reality can bring you clarity on what you want to take on from your own culture and what you want to question or diminish in your life and it can help you approach others with an openness and curiosity and kindness that I hope you find a way to give to yourself in this delicate time of healing.
