That anxiety I get when I try to make a generic, nice comment about seeing a certain character from a comic I like reading after not seeing them for so long because I read my bookmarks once a week, but end up getting on the author's nerves somehow. Uncommon for me, but that's why I try to be as inoffensive as possible.
As a side note, I suffered from severe anxiety so much during my high school and college years that I literally almost died back in 2015 due to Graves' Disease, which is a constant over-stimulation of the thyroid gland that regulates adrenaline. My heart hasn't been the same since. Shitty co-workers don't help my condition either, as the disease is starting to make a comeback.
