I love my son and need help

[Kate]

I live in South America and I’m the mom of a 19-year-old that is going through an awful time starting from when he started taking finisteride 1 year and ½ ago due to hair loss which he took until a month ago when he stopped taking it. During the time while he was taking it, he was hospitalized twice with psychotic episodes and was given far too many meds and we later realized it was due to the finisteride and he had no diagnosed mental problems.

It has truly been a rollercoaster of emotions and physical side effects of this damn drug which seems to have drained him of his self being and I am extremally worried pissed off and saddened , he used to enjoy listening to music and reading a lot of books, exercising, riding his bike, working out with weights, generally but at this time he cannot do any of this because when he does, he feels fatigued and is worse. He has a range of symptoms like the following: depression, panic attacks, loss of libido, anhedonia, chronic fatigue, less muscle and less strength, anxiety, mental fog, awaking in the night, suicidal ideations, despair, testicular pain, amongst other.

He did feel better during 3 days where he was with enhanced mental capacities and taking interest in various areas and a little better physically.
He is at this time taking vitamin B6, K, zinc, and magnesium citrate.
Today he had a mini crash of some sorts, he took some tribulus pills and made him worse. The few times he has done exercise, he has felt way worse. On one occation he went to the supermarket on his bike and felt significantly worse afterwards. Why exactly does this happen? Is this some kind of androgen sensitivity in regards of androgenic herbs and exercise? If so, will this change with time?
My question is basically how he can reactivate his 5AR enzymes and to build up his androgen levels and if there is anyone who has recovered whom I can speak to personally?,

I fear that my son is near collapse and I don't trully know how to handle this or trully cheer him up; well more than cheering him up, I want to inspire him with someone who has personally recovered - show him that there's a way out of this hell.

Thanks for reading guys.
