Tilly, firstly here's huge hug.
I can't help but I can relate to your post.
I too had a 6 year old at 44

I'm 49, so he's coming up to 11 now

- and I'm on this 'treadmill' as you call it too

Are you taking HRT or not?
I started taking HRT back in November after starting with flushes, looking ba\ck I didn't realise I was perimenopausal but I was - moody, irritable, tearful, baaaaad PMT.
Well when I started with HRT it all got worse - well, better and worse!!!

, hot flushes went straight away which was great but while on the progesterone phase of the HRT my psychological symptoms have got worse!!!!
Much worse!!
I felt just like you posted - that I couldn't carry on, my life felt like it was over, felt undesirable, fat (can't manage to lose weight now like I could before either!) skin dry and horrid generally like a waste of air - mother nature is one mean bitch!!!

Last month after being in the pits of utter despair after wanting to walk out on my hubby and kids as I was making their lives miserable with all this I was allowed to try a different progesterone called Utrogestan.
Now while I haven't felt 100% on it, I felt 95%, just a bit of general flat mood.
Strangely though, I've felt more 'flat' and 'meh' whilst just coming off it while on it?
Just wondering if you're affected similarly? Progesterone intolerant? I know its not the answer for everyone but considering I'd never heard of this intolerance before I started on HRT I think other ladies ought to be at least aware of it.
I've always been affected by hormones - PND, PMT etc so it all makes sense for me anyway.
I'm hoping for a miracle cure - there I've said it! But I know there isn't one.
Hang in there Tilly, keep chatting on here if it helps, the ladies on here are amazingly knowledgeable and supportive! xxx
