Just embrace it.
Last night while talking to my friend, she also expressed the same thing. She said, "I dont know why, but I need the feel to be detached from people and go into my shell many times." I told her not to worry and embrace whatever it is.
It is a part of you also, Jenine. The world may think whatver it wants to. But be true to what you are from inside. If you need space, then be it. Maybe you are already self-sufficient and don't need anyone to validate it for you. Maybe it is your healing space.
No need to explain it to anyone, no need to understand. Just be what you are.
Enjoy your beautiful company. 🌹
