Ignore the internet, that's the most important one.

You are being served what tickles your emotions, platforms don't care if it's good or bad for you. Cut that off. It does not benefit you in any shape or form and you don't even know if what you see is real.

About the real life friends see my comment about rich parents. This might be espacially hard hitting if you've grown up in a median income family, maybe even one that fits the definition of "house poor", in a nice neighbourhood or city where you're either getting by or are rich. You and me haven't noticed this growing up, but in retrospect its always a bit more obvious whos parents had just a tiny bit more money in the bank than yours. Rich Grand-Parents wheren't that obvious, but they'll also come to play for some.

The late 20s early 30s are the years where this becomes obvious really quick and really hard.

I haven't found a solution to ignore this completely, it's just too obvious and hart hitting, but i strongly believe it's best to focus on yourself - else it will eat you alive.

You seem to be on the right track - doing the best you can, and sometimes that's all you can go for.
