Kaytee, I think we are in a very similar spot!

I'm in the process of applying for new jobs at the moment, my current job is destroying me, resulting in tears, stress and me being a completely horrible person to live with.

I have had second interviews for 3 different roles and hoping I hear back from one ASAP.

I have realised I have been loyal to my company for many years, but I am
not getting what I need from them. A few years ago, I would have done anything, but I now realise it's time to put me and my family first.

I can't have DS and DH have a miserable mum and wife.
Ultimately no "job" gets the good me.

I haven't told my boss what I am doing, ultimately it's none of their business and if I'm not successful in any of these roles, I don't want them to make life harder than it is.

I think you need to do what is right for you, and if that's looking for a new job now, then do it!

Good luck, I know how tough this working mummy gig can be.
