With apologies to Frostycake for hijacking her thread (perhaps she will feel a little comforted by the thought of others struggling too), I feel for you saythatagain I really do.
My situation was complicated by the fact that I live overseas, and was previously in the Netherlands, where my doctor refused to prescribe HRT for more than 3 months. I tried to argue for a long term prescription (there are no cancer, high blood pressure medical histories in my family). He wouldn't budge - he said it was medical guidelines in NL. I might have remarked snappily "well 3 months of HRT isn't going to bloody help, is it?". I might have said that quite loudly as well. And then cried.
Due to brain fog, depression, and lack of energy, it didn't occur to me to google "menopause uk" and read up on it. Or even look at the menopause thread on Mumsnet. Sad, eh? In my new country, I saw a GP privately, and was eventually prescribed Activelle. Before getting that, I was given mild non-addictive sleeping tablets and a mild sedative for 4 weeks, the name of which will come to me - no it won't, begins with an 's'. Still takes time for the memory and brain cells to come back - sorry.
When you see the doctor, ask about HRT options and get what you can. I couldn't tell you what's in Activelle - I would have taken serum from snake's pee if someone had told me it would help, that's how desperate I was. Activelle seems to be OK - the ideal is to have bio-identical HRT and nothing beginning with 'prem' as that's made from pregnant mare's urine. Seriously.
If there is a delay in getting a prescription, ask for mild sleeping pills and a mild sedative. Tell your doctor about your anxiety, and sleeplessness and how it's affecting your every day life. Tell him/her they will be writing you a sick note if they don't give you something to get back on track. Don't leave without getting something. In the meantime, look at the menopause threads - some are seriously technical (some bloody smart mumsnetters out there!) and others just have tips on websites, and what not to eat or drink. That tends to include coffee and alcohol. I limit it to one coffee per day and a couple of smallish glasses of wine in the evening.
You're not alone. There's millions of us worrying, snapping, crying and gaining weight together.
