brown I hear where you're coming from. And if it's any consolation, once the DHEA is out of your system your skin WILL return to normal. I have to say, it took a good couple of months, possibly three, before I felt my system was back to normal, before I saw all side-effects gone (facial hair, excess sweating, etc).
I have to say, this is exactly why I'm steering clear of another FSH test, or the AMH one. I'm 100% certain they will be rubbish, and I don't want to know, to be frank. Even with low AMH/high FSH there IS still a chance of a natural baby (assuming IVF isn't a possible route) - it doesn't mean there are no good eggs left, just less of them. But there does indeed have to come a point where you have to stop throwing your all at it, as it takes over completely.
What makes me wonder is the number of women who get a "surprise" pregnancy after they've stopped actually trying. So many people saying taking the focus off (and so reducing the stress) seems to do the trick and I suppose that may be true.
Other than doing OPKs each month (and taking my supplements of course), I've pretty much reigned it all back in. I'm not taking pred and I stopped hydroxy too (hopefully the Wobenzym is doing the trick there, but that's natural and not chemical so I don't mind taking those). And I'm not seeing Mr S right now - I can't say I definitely won't change my mind about restarting SO at some point, but not for the immediate future, certainly not this side of the summer I think. I don't have much hope myself, but I am not going to completely give up.
I think you're absolutely right in focussing your attention on the rest of your life, and learning a language is always a wonderful thing to do - especially if you can then share that with your son. Don't be a stranger though, we all would like to know how you're getting on :)
