Hello there

I'm feeling a bit lost and confused.
I am now 45 (in June), and have suffered with various symptoms since my early 20s (at least). Some of these symptoms have increased in their severity over the years and then some new symptoms have slowly incorporated themselves into my life too.
These symptoms include, but are not limited to: bouts of physical fatigue, non restorative sleep, constant sore throat, random sudden onset pains in my body (anytime and anywhere!), back pain, brain fog and issues with concentration or finding the right word (honestly, I feel utterly stupid sometimes!)
I've seen various GPs about these issues on and off through the years, and have been told that they're just due to my anxiety issues, or my depression, or that they're just fitness issues... etc.
Last year, my GP saw a correlation with my age and these symptoms and concluded that I was probably peri-menopausal. A blood test came back with an elevated FSH level, and she was convinced that her diagnosis was correct...
I asked if my Progestogen pill (Desogestrel) may have had an affect on the FSH level recorded in the blood test. The GP advised that I should come off it and then we'd test again. So I did, and the level was still a little elevated, but not at a conclusive level ("Not as high as I would have liked," said my GP). However, my GP wanted me to try HRT and I agreed - it was worth a try if it could see my symptoms eased.
When I first started taking HRT (Utrogestan and Oestragel), while I was off the pill, I started having bleeds that lasted 3 weeks, then I'd have 1 week off, before another 3 weeks of awfulness. Before that, my periods had been fine and normal. I told the GP and she advised I went back on the pill because it had previously stopped me from having periods. I did, and they did mostly stop but I had spotting when I'd not had any before on the pill. I knew I needed to stay on it for at least 3-4 months to see if I noticed any difference with any of my symptoms...
I didn't notice any difference with my symptoms and so I went back to the GP, and she said, "Well, HRT won't help you with any of the long term symptoms you've been having." Me:
So, I said that I would like come off HRT as I had actually seen a slight increase in some of my symptoms. I had continual leg pain for the whole 3 months I was on it too (new symptom! Yay), which was the first time any of my aches had lasted that long. When I came off it, the leg pain started to subside, but that could have just been coincidental.
I've recently revisited the issue of my symptoms again with my GP, because I am just fed up and want to know what's happening with my body, and she did another blood test. My Vit D levels were a bit low, so I'm taking supplements for that (still waiting to see if it makes any difference). She also took another FSH level read, which I didn't know she was doing, and that has come back high again... so she's mentioned HRT to me again and wants me to think about it... However, after my chat with her, I realised that the test had been done while I was taking Desogestrel again... so I am not sure how reliable it is anyway??

I'm due another blood test in 6 weeks, and so I need to ask my GP if I should come off the pill in preparation for it.
I don't know what to do, though. I do know that I am now in the right age-range to be peri-menopausal, and I certainly could be... but I am not suffering with hot flushes or nights sweats or any 'new' symptoms that could be caused by the lead up to the menopause. I don't know what the point in taking HRT is if there are no symptoms that it can help me with, and I am worried about my current symptoms becoming worse again because of it.
I am also feeling completely unheard by my GP. She's so hot on diagnosing menopausal symptoms (which is great in so many ways!), that she is ignoring the fact that these symptoms may have another root cause. My symptoms may have increased in the last few years (from Sept 2017), but I have had two reasonably traumatic experiences in that time, and feel that the increase in my symptoms would be more likely to be connected with those (especially as HRT had zero effect on them).
Has anyone else had anything like this happen with them? Or, does anyone have any insight/advice to offer me?
Thank you so much for your time if you read all of this - it was a LOT, sorry!
