First and foremost, love your email username! One of my favorite flippant responses when someone is gaslighting me is "Beam me up, Scottie!"
Importantly, I would not assume that seeking help for depression automatically means you'll be taking antidepressant medication. First, you call the shots as to what meds you put in your body and which you don't. Secondly, merely getting into psychotherapy with a therapist who you can work with can work wonders.
Amidst several bad decisions, I made three brilliant decisions when I knew what I was facing: (1) leaned on family and friends; (2) once I knew I'd be going on ADT for 2 years I hired a personal trainer and have trained with her for 2.5 years, losing 40 lbs, gaining strength and, get this, having a blast; and (3) started seeing a psychologist every two weeks the moment my post-RP PSA came back at 0.091.
Ignore the various bits of excellent advice she's given me along the way; the mere fact that I've been able to meet with her every 2 weeks and dump every emotion I'd been experiencing out in her office. Dealing with this disease and side effects of treatments is a heavy burden for all of us. You can't deal with all of that on your own.
Hang in there!
Thanks. The personal trainer story is encouraging. When I started ADT, I bumped up my weightlifting to four days a week instead of three but am still losing muscle mass and strength. The psychologist is an excellent idea, just from re-reading my own post I think I need it!
