Yes, chronic stress will cause this to happen to you. The kind of thinning you have is classic for that. You are not alone in that. I'd not do the finasteride, but the minoxidil may help.Are you seeing someone about the GADCSS? You may need to take an SSRI or even a benzodiazipine like Xanax. That will be key in treatment program.
I don't know. It looks pretty bad to me.
