I absolutely do not want to discourage you from doing a treatment but one thing to keep in mind with ADT is that it takes a long time to wear off. I was on Orgovyx (the supposed "faster" one to wear off) for six months and it's now eight months later and my testosterone is still below normal and I have some side effects. My doctor told me it could be up to two years after stopping to recover as much as I'm going to from ADT, and that there's a 25% chance my testosterone will never recover beyond what it is now (200s, low normal is 300, normal is 350-750). Of course, I was told this after the fact. Ask your doctor what the odds of recovery for you are at 6 months, 1 year and 2 years after stopping and be sure to get a baseline testosterone test before starting.
Also, if you decide to do ADT, get a DEXA scan to see how your bones are as, besides the obvious effects of ADT/low testosterone on libido, sexual function and ability to reach orgasm (which you may or may not care about) it can also cause bone loss. I lost quite a lot of bone on my DEXA scan a couple months ago from what had been my baseline. Weight-bearing exercise is critical to help preserve bones and muscle.
Finally, SOME guys on ADT will get severe depression and try to brush it off thinking "oh, I just feel this way because I have cancer" but it's much more than that and I waited too long to see a psychiatrist about it. When I did, I was put on Bupriopon and it helped a lot immediately with the brain fog/ADHD and over 3-4 weeks later with depression so if you DO decide on ADT and suddenly feel extremely depressed get it taken care of sooner rather than later.
Good luck with your treatment whatever you decide.
You made a very good choice writing about your depression here, then seeking peer support and professional counselling. It's been inspiring watching your progress.
