Definitely not an absolute truth. Every individual have different reactions. Something true for one person will not be true for others.
I'm not qualified to talk about your girlfriend, but we can clearly see origins of her depression. Some people aren't depressed because of some tragic life experience, they are just depressed because at some point their body started producing the wrong hormones ( or whatever).
Medication can help these people without taking them into the vicious circle you describe. I think it's different for every single individual.
I personally took medication at some point, I quit when the doctor advised me to quit, and I haven't needed any pills since then. I've been against pills for a while, thinking stuff like "I don't wanna feel well just because of pill and not because I'm really feeling well" ( and various shit like this)... but in the end I don't regret taking the medication.
No no, this is not a good advice imo.
Friends and family will judge him, no matter how nice they are and how much they love and care about him. It can change a relationship forever if he just puts all his thoughts on the table like this.
Also, friends and family do not know where to seek in his thoughts, they can't make the difference between what is relevant and what isn't, they can't figure what he may not know himself.
I mean, we all have thoughts other people aren't able to even imagine or figure... sharing these with some that may not understand and will judge him is definitely a bad idea.
A psychiatrist will help him to sort this out. He will find what is right, what is wrong, he will reassure him on what is "normal" "common" or not. He will probably help him to figure out what to share with his family and friends, and what to keep for himself, and in the end feel better with himself and with his surroundings.
