I think most of those are meritless. I know they feel like strong emotions, so not to downplay them, but here's what I mean:
"What is my worth" - That depends. There's a quote: "It's no good measure of mental health to be well adjusted to a sick society". As "society" behaves as if the rest of the planet isn't important, and pollute the air, ocean, and land... to be very useful to this society is to be DETRIMENTAL to the planet.
"Have I helped better another person's life" I stopped caring so much about that. I've found people to be petty, small minded, judgemental, and rather stupid, on the whole. The kind of people who'd judge me as a child molester because I like babyfur smut are an example. Meanwhile, I don't even like actual kids. They drive my anxiety through the roof. I just like to get diapered up, act rather "cubbish", myself (it helps destress from adult worries... and is somewhat kinky, too. So no harm, no foul).
"Does anyone notice" I've learned to dislike excessive attention, in light of the hatred I've received over something so harmless to kids as my own interests.
"Am I seen by others in a positive light" That's VERY subjective. No matter WHO you are, SOMEONE is going to hate you? Black? There are people who hate "ni**ers" in the world (not I. I hate humanity almost equally across the board, after all I've seen in life). White? There are racist blacks, as well. Poor? The rich think you are pathetic lazy scum. Rich? Then I, for one, hate you, for lack of opportunity in my own life, and for being told by so many rich people that I suck because I wasn't able to inherit billions from a rich daddy.
Many questions we may have in life are often subjective, and a matter of semantics.
Sorry if I couldn't answer or solve your questions. I'm just answering as honestly as I can, based on almost 50 years of dealing with people. I hope it still helps you sort things out.
