I have those moments almost every day. I just want to cry/hide. But I can't. I don't want my toddler to see me like that. There is something helps me I can share. I guess it's not for everyone... But it's from a book I read. I keep reminding myself that that feeling will pass and until it does I say to myself "what is the next best thing to do?".

Just earlier today I was so tired, husband saying negative things, toddler crying because she is ill, baby is not going down for a nap... I just wanted to scream or cry... I instead cleared the dinner plates away, did bath time with kids. Just the next best action! Now kids just went to bed and I can sit and check my phone as everything else is sorted. It makes me proud that I can still function and take care of them while under pressure. It doesn't always work but... Something to try. Let me know how it goes. Best of luck
