Sad... when do I just give up ? Who do I talk too?

I just pumped and not even an ounce came out... I have no idea why.

Last night in desperation because I was alone, I tried to get my son to latch (he’s never been consistent) he did! He nursed and then slept for like 4 hours!

This morning I thought I would try again, he screamed and screamed and wouldn’t do it. So I gave him a bottle, then went to pump and nothing was coming out 🙁 I’ve had an okay supply before then and I pump religiously. I was always just enough.

But now it’s dwindling and idk if it’s from stress or what.

When do you throw in the towel and start formula ? Anyone have this expierence
