Hey man,
I understand what you are feeling now as I have been through the same shit myself. It’s hard to believe the UK doctors could be that ignorant(I’ve heard they’ve already added sexual dysfunction to official accutane sides in the UK). But I also had to face the misunderstanding from doctors, who told me it’s likely to be psychosomatics. Like hell it is!
Although we don’t know what exactly is going on, it’s definitely not “something in your head”. So you have to prepare for some fight. And it will definitely takeat least some time. I’d be really glad to tell you, it’s all gonna resolve soon but for the majority of cases it’s not true. But it’ll be better with time, and I believe we can expect full recovery. You just need to carefully monitor your condition as you can experience some changes (at least I did) and never give up(especially in your age) even it reminds you of hell.
I’ve also been through some medical screening (all the details in my topic) and like in your case almost all test results appeared to be fine. I’ve found only two things that fall out of norm: very low progesterone and too high 3-alpha-diol-G. I’m curious if yours are the same.
So, don’t give up, you’ll see some improvement or even full recovery(before developing long PAS, I’ve experienced an episode of pretty much the same condition, except I recovered fully quite fast, I didn’t even understand what happened to me at that moment).
Take care
