You've gotten tired of relationships, haven't you? First, please forgive yourself for that heartfelt voice saying “I don't want to be interfered with by anyone.” Now that I have closed the door to my heart and am in a quiet period of protection, there is no need to force myself to get involved with people.
Still, “feeling lonely once in a while” is proof that you're still deep in your heart and looking for a warm connection with the world. It seems contradictory, and this is a very normal function of the mind. What should I do when I feel that loneliness? My suggestion is to “get involved with things that aren't people.”
Humans inevitably interfere with each other with words and emotions, but nature and Buddha are different. The moon in the sky, the roadside flowers, or the serenity of a Buddhist altar. They don't demand anything from you, they don't evaluate anything, they just “stay” there. In Buddhism, this is called a “silent sermon.” By focusing on beings that are beyond words, loneliness can be transformed into peace called “silence” without the hassle of being interfered with.
When you're lonely, don't force yourself to find someone; just drink tea quietly or look up at the sky. “I'm alone, but I'm not cut off from the world.” It's enough just to feel that way. Like Amida's light, the warmth of watching you silently is always there, even if you can't see it with your eyes.
