Thank you for writing on this platform. It must be very difficult watching your brother go through a hard time and not being able to do anything about it, despite your best intentions.
I understand that you are very concerned about your brother and his well being, and do not want to see him suffer or be alone during a time like this. I also appreciate how supportive you and your family are being and how you are trying your best to get your brother also to see and realise that he in fact going through depression.
Sometimes presenting them with facts and letting them think over it helps. It may be so that your brother is aware of this, but is having a hard time accepting it and so does not wish to hear it over and over again. Having a taboo against such an issue is common and can be difficult to overcome. Showing them that you care through your actions and behaviour can be very helpful at this point.
You could keep trying by talking to him and making him understand that you just want his well being and that just a single visit to a psychiatrist is not going to mean that he actually has something. It can even be a visit to rule out depression and see what else could be affecting him which can be making him appear as though he is undergoing depression.
You could also suggest him to use this platform as it is anonymous and a place where there are many experienced psychologists, clinical psychologists and counselors. It would do him good to have a talk with one of us and understand what he is going through. We are available on chats, audio and video. Face to Face sessions are also an option if he would be comfortable with it.
