What do you think of those who send or delete friends?

As an obsessive-compulsive disorder patient who silently deletes a circle of friends every few days, he is often asked by friends, why did you delete another circle of friends? Did you delete them one by one? In fact, sometimes it is really a kind of psychology. After something that is fun at the moment is sent to a circle of friends, it seems that there is no need to send it the next second, so it is deleted. In other words, I have been paying attention to how many praises and comments I have after posting, and then I hate myself and care about other people's comments, so I deleted them. Well, finally, sometimes I just want to maintain my image with special affectation. If I feel that my circle of friends is not suitable for the image I have always created, I will delete it.
