Don’t know what I want to do with my life

I am having a hard time deciding what I want to do with my life.
I had some health challenges in 2019 and currently going through a divorce. My children have just started university and living with me. Both of them are trying to figure out their way and need support (financial, and emotional).
I feel trapped because I feel obligated to take care of them and not do me sometimes.
Currently I have been thinking about moving to a different country to live by the beach. I don’t know if it is me trying to change my C or if it is a real need.
