Your post surely makes a lot of points, so I will divide it in a few pieces in case you need my words.>Anon, are you sure you're sure? Because I am not.
Even if we are in the middle of a pandemic, I am still certain of being sure as I am knowledgeable of what should I do that can: 1) either be an action for my own benefit 2) or an action that I will not regret in the future as it could be considered a "future-proof" action and, inherently related, decision.
How do I know? This is 100% related to the next part.>How do you know what you're feeling, or if you're feeling anything at all? I don't know why I can't understand my own feelings,
As per the famous quote, "I know that I don't know," it is true that there are some things that we do not know whatsoever.
However, we are in the 21st century and we are now perfectly able to search all over the internet on what do we want to know. So there isn't really a good excuse on not being knowledgeable of whatever topic you may have an interest on; unless you have some kind of disability, and even then, there is still a way to know, for which it is inherent in human nature to know.
Else, we would still be living in a le monke society.
But to answer your question, my own version of the quote I mentioned is:>I know that I can know
Why? Because there hasn't been a greater, golden age-like present in all the history of humanity where the modern "clergy" (i.e. university professors, higher level professionals, etc.) have been very good-willing in sharing on what they know, as well simplifying it to the level of the "laity" (i.e. the common people) so as to know many of the things we don't know, but, for sure, we can now know about them–even without the need of a psychology degree, or so.
Having this in mind, I will give you the homework of googling what you don't know in order to know and be sure; attempt to find the words to describe what you are feeling, search the said word's definition and its related ideas (e.g. why do I feel that way), and, most importantly, as well the most difficult task, is to attempt to have a higher level of knowledge on your own self and your surroundings so as to be very sure on understanding your own feelings.Post too long.
