This reminds me of a quote by Rainer Maria Rilke:
But your solitude will be a support and a home for you, even in the midst of very unfamiliar circumstances, and from it you will find all your paths.
I would travel. Go somewhere by myself and walk. Or, alternatively, join a walking holiday with others on their own (if you like walking!) It doesn’t have to be outside your home country if going abroad would be difficult.
You don’t say what country you now live in but if you are outside the UK then come to the UK and do one of the National Trails. Or a pilgrimage (doesn’t have to be religious but there are many pilgrimage sites where people have walked for inspiration for thousands of years).
If walking isn’t your thing, then you could find a retreat somewhere meaningful for you. Again, it doesn’t have to be religious or faith-based; there are many retreat centres across Europe where you will be welcomed for a time of renewal or to learn a new skill - yoga? Meditation? Art? Painting holidays? Cookery? Wine tasting? Or just time by yourself. You may make connections with others during this time which will offer you a new perspective.
Whatever you choose to do, take a risk. If you don’t take a risk things will stay as they are. Taking a risk may lead to refreshment and happiness. Do something different to move forwards.
I wish you all the very best.
