I'm sorry you're stuck in this situation for a while. Yoga and meditation are definitely a good start but I feel like adding either journaling your TRUE feelings about what is going on or talking with a therapist or trusted friend about the things you really need to get off your chest–because leaving all these things you feel you need to say unsaid is obviously making your life harder.
Solo travel is the besssst. I tried it tentatively shortly after my divorce, too, and it was a great experience. It’s really helpful in that you get to take some time to focus on being comfortable with who you are as a person (not someone’s spouse or whatever but who YOU are.) No work or other responsibilities to distract you, so you do a lot of self-discovery while exploring a new place.
I don’t have a lot of travel tips because I have always been not really able to afford international travel except for very recently, but I am so proud of you for stepping out of your comfort zone and taking that step. Now you get to start the countdown and planning for your comfort and safety during travel. I personally love that part, but I know not everyone does.
