People's sympathy feels so insincere to me. They care in the moment, which means that they stop caring soon after. I would much rather have one person with whom I can share my thoughts to get a second opinion on what I should do than to have a dozen people tell me they are sorry for me.
Sometimes I receive misplaced sympathy too, which I definitely dislike. For example, I like to stay at home in my free time. It has happened a few times that I got sympathy pitied by some extroverts when I told them that I didn't have any plans for the weekend and would be staying home. I understand that they don't like the idea of staying home alone, but I do.
Edit:
I forgot about the part of when loved ones show sympathy. The above applies to my family and friends too. I don't like to be reminded of my misfortunes for the sake of showing sympathy—positivity is vital to me. But I appreciate anyone who wants to help me. For example, by reflecting on my mistakes with me and giving me a second opinion on what I should do next.
