I recently I found myself struggling with a personal/relational issue. Unable to resolve it, I struggled and thought about it and felt uncomfortable. I think this could be called anxiety, though I don't really use that term when describing myself. Regardless, I came upon the following quote and all of the sudden, I'm comfortable. So I'm giving it away here, hoping that it can relieve anxiety or stress for you, too.
...have patience with everything that remains unsolved in your heart. Try to love the questions themselves, like locked rooms and like books written in a foreign language. Do not now look for the answers. They cannot now be given to you because you could not live them. It is a question of experiencing everything. At present you need to live the question. Perhaps you will gradually, without even noticing it, find yourself experiencing the answer, some distant day.
Rainer Maria Rilke
