Hello Karreb73. Welcome to the forum. The constant needing to wee is known as vaginal atrophy. Low oestrogen causes all sorts of bladder and vaginal symptoms such as not being able to empty the bladder, constant needing to wee, UTI type symptoms, pain, dryness. You need to get some localised oestrogen to help the area. This can be in the form of a pessary or cream and it will also help to get some vaginal moisturiser. Yes and Sylk are nice and gentle.
Not sleeping and anxiety are sadly very common meno symptoms too. I am sorry you are dealing with this but you are not alone.
