I’m truly scared that I’ll amount to nothing in life.

That's a really extreme thought

Nobody can amount to nothing. The fact that you've achieved things already tells that you've done and amounted to good things

I guess the aim is to think about doing and achieving more and perhaps thinking about more purpose :)

You're really capable, amazing, and far more brilliant than you know

Everyone has that feeling at some point. You're not alone.

I've felt like that sometimes...
But then I also think about how we're all going to end up d3ad some day.
And our accomplishments will be soon forgotten, along with us, and nobody will care.

That’s a good place to start, now go do everything that you’re scared of doing that you really want to do.

I’ve just sort of accepted it at this point. A lot of shit happened, so it is what it is.

only you can change that, your destiny is in your hands, as it is with all of us.

Been there done that.
Don’t be like me
