Hello, I've watched and learnt a lot of useful stuff through my DP's use of MN but have never felt compelled to add anything.... until now!
I don't have the same amount of little un's as you Mr OP but I can recognise many of your pent up frustrations. That's what they are though, frustrations. The apparent lack of control over everything.
Somebody posted an earlier comment about being anal about the loo being clean. I don't think it anal about wanting to maintain personal hygiene and general cleanliness about your home. These are the standards that you have set for yourself and wish to uphold. However, sometimes something has to give. Hey, it's be clean for a while, by tomorrow it'll be back to where it was.
The important thing is to get perspective on the bigger picture and what is important in your life. Clean loos? maybe but is it really worth stressing over?? Surely not when it comes to the love and happiness of your family.
My DP gets up at 5.45 every day and yet I don't have to get up until 7am. This sucks. This has now been compounded by the fact that our DS now gets up to join us, bright and breezy, announcing that the day has begun at 4am!! This sucks even more and we are both feeling it. Both of us, as in team Mum & Dad. You are feeling it but so is she.
Stick together, work out your own 'me' times because it's important for you both. Recognise when your other half needs a break and make it clear when you do too.
As for the stress at work. When you feel that you are up against it and feel you can't win... well, jut imagine and picture your family in your mind and recognise for yourself that they are all you need and the idiots you contend with at work all day... well, in the grand scheme of things.. they don't really matter. They don't really matter at all.
