How can I mentally evaluate my anxiety?

I just want to preface that I'm currently enjoying life. Especially with friends who support me and a career that actually fits me

But i just had a panic attack and started having obsessive thoughts over the choices i could've made career and life wise before now

Especially how they likely would've been detrimental compared to the ones that are working out for me now.

And it could've ended up with me having to get to where i am at a later age?

Which certain people (especially family) would look down upon me if it happened

Not that i look for anyone's validation

But getting stuff done and realizing things at a later time than "usual" is a massive worry of mine. And i don't really understand why

It's likely because of external voices (family) and events (economy, AI, government) than anything

How do i handle the fact that I'm living a great life right now, but constantly worry about the choices i could've made?
