Square covers like this are common globally. AFAIK also in the US:

Setting square tiles or paving stones around a circular cover is a pain in the ass.
But it wouldn’t be the first time the US is weird, like the whole imperial measurements thing, so whatever. Or maybe you live in a state that decided square manhole covers were biblically incorrect.
I can relate, so I’m not going to tell you things get better. You probably wouldn’t believe me, I wouldn’t believe you.
Just to say, you’re not alone, I understand why you unhappy, it’s perfectly understandable that you’re angry/sad/tired. The world is shit. People are shit. Life is shit.
If I was to give you advice, I’d perhaps say buy a lottery ticket for a few bucks, pop it in a drawer. My logic has always been, that given my luck, I’d probably kill myself only for my ticket to win the lottery. One last cosmic joke. So I use this to delay for a few days or weeks. That or I book a ticket for a movie or make plans from a week from now.
That and distract yourself with tv, games, audiobooks or whatever. I’d say read a book, but I suspect that like me, that’d be hard to focus on. Anything that stops you thinking and offers an escape. Anything to delay for another few days or a week or two. Oh, and spite also helps in the short term. Outliving the bastards who made or make your life shit. Maybe there’s a hateful politician you dislike who’s old and might die soon. Might as well delay a few more weeks for that. Wouldn’t want to miss them dying.
My comment probably didn’t help. I probaby worded it poorly. But I hope you know you’re not alone. That people do want you to succeed. I wish I could give you a hug over the internet, that it would help, or perhaps make a plan to go to Disneyland or some shit to distract ourselves, but this is the internet so that’s not possible.
