Literally what I thought while reading the manhwa with Penelope (the title, unfortunately, eludes me at the moment). The situation was so depressing I thought I'd kill myself just so I won't have to handle it 'cause bro I'm SO TIRED and everything that was happening was so mentally and emotionally exhausting. Peace of mind is just out the window lmao. Like, atp I'd just set myself free... By dying. I don't know how she does it!
I know which one you're talking about. I've been keeping up with it and I agree. What makes it worse is that she couldn't die even though she wanted to. There's basically no escape. I'm already depressed in my situation but if I got thrown into what she did out of nowhere, I wouldn't want to continue living either.

If I get isekaied, I'd probably die due to stupidity and being a slowpoke
