However, no one forced you to read the OP, and I am certain she didn't write it to annoy you.
As you don't actually have children as yet you have no basis to tell the OP that its not that bad, and it's really a bit awful to have a go at someone who has come here seeking support- the title SAID it was a vent, that may be why you didn't see anything positive in her post. She is here seeking advice to help with her problem, what more do you want of her? Goodness.
OP- I second the daycare idea, you poor thing it really sounds like you need a break! Also, have you considered a play group? You can make friends and your son will love it!
