I understand what you mean, and I'm here to give support.
Here's some impressions I have...
You're young.
You have an incredible physique.
Now as I see it, you're main problem is with sex drive. This cycle aside, have you thought about what you're going to do when this cycle is over? Whatever the case, your HPTA will be worse off (to say the least) afterwards. In this regard, you're just hurting yourself more than helping. I know you've tried a lot of different things, and it's been over a year, but my suggestion is try to be even more patient. I'd go to a few different endocrinologists and explaining what happened to you exactly in the passed with your cycling incident. Tell them how you feel. How was your sex drive before the cycle? In my opinion, I'd give it some more hope that with time you'll go back more towards normal. However, the downside here is that steroids might not be the best thing to be using.
So then I see two choices. One, use steroids and be on Hormone Replacement Therapy (HRT) for the rest of your life (this won't even necessarily give you sex drive, maybe it will at first, but I've seen cases where prolonged usage has caused some people's to decrease from base... obviously with this point I'd ask as many people you know who are on Hormone Replacement Therapy (HRT) to be as honest as possible with how their sex drive has been both before and during) The other choice is the harder one and, if not just for a while, the one I would opt for. And that of course would be to give it more time and see more doctors. Whatever you decide to do, or don't do, I wish you the best and I'm sure you'll let us know how it turns out.
