Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.
I think if you tell people about his death that'll give you some insight as to what to do next if you go by the reactions you get from his friends and family.
I am sorry you feel invisible, like no one see or hears you at the moment. I am here, I've read your post and will be here all afternoon if you just need to be heard. I am in the UK hence the afternoon remark.
I hear you and I feel for you also.
