nicky I've been a sahm for 13 years now, although I have worked on a casual basis for most of that time. I'm ok with having been a sahm, but finding it hard to get back into a "proper" job has left a bitter taste. I'm lucky I'm not broke (yet). Most friends have managed to keep hold of their jobs, and whilst I don't feel envy towards them, I realise that, in order to keep a decent job, you need so much support, and i didn't have that support. So when I realised the only option for me was to do supply teaching which I most definitely didn't want to do, I became very jaded. I'm ancient too, which doesn't help. I'm retraining now, though, finally.
I think the most difficult thing I found was, as most people work, friends for my only dd were not always available. I can honestly say that I found keeping her amused exhausting. People around my way are somewhat cliquey and established family/friend groups are difficult to break into. I'm really introverted too, and losing my identity amidst shouty, confident working professional women at the school gate just rubbed the isolation in for me. They probably thought I was some sort of sad loser, but I wasn't. I was a confident professional just like them-once. They probably didn't twig-or care-that I had 20 years' professional experience! This really bugged me for some reason, although I probably am guilty of overinvesting in work and desperately needed a break.
So, although I kind of enjoyed it -or at least found it easy- I didn't find it fulfilling at all. I liked the baby stage, found toddlerdom difficult and sighed with relief when dd started school. The rest was just dull-filling in time, really. I had no patience with many of the other parents, finding them heavy-going and overinvested in their kids; I found the school's expectations on parents irritating. I was a right miserable old git. Thankfully I found a hobby and hoping to turn it into a new career! Phew!
