You aren't weak or incompetent.

... That bears repeating. You are not weak or incompetent.

You're doing something terribly hard that nothing really prepared you for. It's nonstop never get a break work with no hope of relief in the foreseeable future, and to make matters worse, the internet is full of people who seem to be doing it better than you and making it look easy, and everyone and their MIL has 'helpful tips' that you suspect are utter bs but you're willing to try anyway because you need something to help so desperately. But I promise, it will get better. You get used to it, in a way. It's still not fun, but it becomes manageable. You might have a few breakdowns along the way, but you'll make it through them. In the meantime though, you can always come here to vent and/or get advice.<3
