Well lockdown and the pandemic has certainly had negative affects on many people's mental health. I wouldn't doubt that a single mother of young children may well find herself having a crisis.
Honestly this is the fucking problem with the internet and the illusory connections of social media. People who really need to be helped in practical, real world ways end up consumed with overthinking and write blogs about it, counting clicks as engagement with other humans instead.
Please, everyone. Go outside for walks more, sit next to a few trees and breathe, chat to someone while you're queueing to get in the shop. I read this and yes, I thought it was indulgent nonsense, but it would have been fine if she hadn't needed to put it out there for others to consume. It's a private journal entry, and as such, it's no more ridiculous and navel gazey than anyone else's journal. The mistake is in offering it out, and with it, herself, for the approval of others.
No one else cares about your journal. That doesn't mean it's not worthwhile or meaningful to you. You just don't need to show it to anyone and have them either tear you down or praise you for it. Sheesh.
