I had the same experience from Lupron and just was generally miserable when I first started taking ADT. If you read my posts from last August you will see how bad things were.
My depression got so bad I started having suicidal thoughts, and thoughts of just refusing treatment. I did several things that were helpful. I'm putting down the cost (U.S.) since I know some of these things are expensive but most aren't.
1. Started exercising like crazy. Gym: $20 a month. Walking 3-5 miles: free. Bicycling: Free (if you already have a bike)
2. Joined a support group (free) and this forum (free). Have been attending support group meetings regularly. You can find a good list at Zero (https://zerocancer.org/help-and-support/find-support-group). Some are more focused on physical aspects of treatment, some on emotional/mental and some are balanced. I tried two before finding one I really liked.
3. Began seeing a therapist. $225 a session, my insurance paid $200. If you're on Medicare I think they pay about the same amount.
4. Started taking Wellbutrin prescribed by my GP at the advice of therapist: Cost: $5 a month (with insurance), $15 without using GoodRX or another discount coupon.
5. Volunteer work (free). Let's me help others and do something unrelated to prostate cancer.
I switched from Lupron to Orgovyx halfway through my treatment and things were better, but I don't know if that was due to the change in medication or because I was doing all these other things to feel better. I 100% get how you are feeling. These drugs affect everyone differently. For example, I never got hot flashes. Others never got depression.
I started going to tbe gym and walking lol about the same as you 3.5 a day it does provide some relief for sure I haven’t been in a few weeks contacted covid been out three weeks I plan on returning to the gym next week thanks for the positive input I do appreciate it
