Julia,
I feel for you. Eighteen months ago I was hit like a sledgehammer by menopause. My family felt like strangers to me, my anxiety and dread overwhelming, nausea , sweats , panic, palpitations, crying the lot. I couldn't see an end to it. I'm like you, a doer, I need to nurture people and don't like feeling helpless.
I told my kids my hormones were imbalanced like a chemical imbalance and it would take a while to recover and I would have times when i would cry, be sick, want to be alone etc but it wasn't them it was these wretched hormones, and I needed their understanding.
I have been on HRT for a 16 months now and things are much better now, there is light at the end of the tunnel. If I have a bad day now the kids will say "hormones Mum?" and they don't worry as much about it.
Please give yourself a break , you will feel better in time. Have you tried any ADs alongside your HRT? It might just help you to get your anxiety under control while the HRT stabilises. I know I couldn't have managed without mine.
Also if you have an Ipad or android device get yourself some guided meditations downloaded. You could do them with your daughter as a special time together. Believe me I have been where you are now and it's horrible but it will ease. Hugs xx
