Hi Tass1960

from me too.
So sorry to hear about your menopausal symptoms. I totally agree with the others re treating vaginal atrophy with local oestrogen so that's the first thing to sort out. Ditto re the diazepam - your doc should not be prescribing these because your HRT does not suit you!
One of the reasons you may be experiencing problems with HRT is because you have been given continuous combined HRT which is correct for someone who is post-menopausal and to prevent a bleed. However both of those types contain synthetic protgestogens and if you are sensitive to these, they can give rise to low grade side effects ( irritability, headaches tiredness, depressions) which as you have found can outweigh ( by interfering with) the beneficial effects of oestrogen.
Personally I would not try the Prempak - I mean this is also a continuous combined HRT, In your position I would want to know if adding a medium dose oestrogen helped with sleep, and joint pain - and therefore would start with oestrogen only and then add in the progestogen. This would mean putting up with a bleed every month - but at least you would know which progestogen you could tolerate and if none, then you could ask for a referral to a menopause clinic and perhaps go for a shorter course per month, or a longer cycle, under supervision.
If you decided to go down this route then there are cyclical versions of the same patches ie Femseven sequi and Evorel sequi to try, or do what many of us do and take oestrogen separately from the progesterone ( tablet, patch or gel) along with the bio-identcial progesterone ( micronised progesterone) ie the same type that our bodies make and so less likely to cayse sdie effects - especially if used vaginally.
The other option is having a Mirena coil which slowly releases progestogen to the uterus where it helps to keep it thin - which means you can just add oestrogen at the level that helps you and apart from some initial bleeding and spotting eventually stops any bleeding altogether.
Finally there is a product Livial (Tibolone) available only to post-menopausal women which is not like other HRT but is also no-bleed and is very helpful for libido as well as giving other positive effects. Some women love this!! There are some threads going on at the moment.
I would resist taking any form of AD, betablocker ( which is a heart medication) without first trying to get the HRT right - if your low mood etc is hormonal rather than something you have experienced throughout your life. Low oestrogen can cause low mood and anxiety on a long term basis - you just lose that zest for life.
All the HRT types are listed above top tabs - treatments/HRT preparations.
Hope this helps and do ask if there is anything else we can help with - hope I haven't confused you
