I've been going through some similar struggles recently, but I found some unexpected clarification in reading some Dave Ramsey books which were about finances and business, nothing at all about neurodiversity, but which clearly showed that a lot of "normal" social expectations aren't really all that healthy or sustainable, much less "successful," nor really producing as much long-term happiness, stability, or positive relationships as we may think.
A lot of what we perceive as visible accomplishments are financed with stupid amounts of debt that ends up enslaving or destroying people rather than getting them ahead. A lot of what gets acquired early on in life gets damaged or lost later due to not having the means to take proper care of it.
If there were a way to see the real price being paid for all the trappings of success that get flashed around, they probably wouldn't seem all that successful or desirable anymore to want to compare to, and just not having massive amounts of debt is a huge advantage and accomplishment that'll put you ahead of the "normal" majority even with relatively modest means. A small amount of positive is still greater than a large amount of negative, even if appearances don't always make it feel that way.
But even if that weren't the case, even if we were really doomed to always be running behind, life itself is not a race, nor is there even a common destination to be aiming toward. At the end of all things what's going to matter is not how much did you do or acquire, but did you enjoy it?
