Hi,
I am in very late peri and have had pretty bad symptoms from later on in 2017 with long phases of when I felt completely awful during the day, nauseous, dizzy, anxiety I never suffered from before all this, and completely exhausted even after sleep etc and lots of other symptoms, all this can be part of this transition unfortunately. I am now slowly improving but it is a slow process. It may be worth picking up with your GP again, and for HRT if you find one that suits you that may help. I have not been lucky with HRT but it can help a lot of women. What helped me most is exercising even if it is just a short walk at times, and a low dose of magnesium for nausea of fizzy drinks at times (not the best option for dental health though). All the best, AG
