I’ve come to the conclusion that what you feel is what you feel. There is no right or wrong.
what about introspection? What about what is considered mentally healthy or not? what about how it affects others around you? If you have past experiences or trauma or other orangic or inorganic neurological or mental issues having a "flat affect" can be "wrong". If what you're feeling isn't helping you, how would you know that there's another way unless you get help?
This sounds defeatist and if you peek just a little behind the curtain this can lead to all kinds of "bad". IMO.
Just imagine the worst thing you can that someone could think, and then they say "it's okay, it's just how i feel, it's not right or wrong." I get that we shouldn't gatekeep or police thought, but obviously this isn't some "universal truth"...
(As an aside, I think of counseling as “optimizing my life”. Perhaps that framing may help those that find the idea off-putting.)
