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.
