This is a touchy one because telling someone they need help does not work. While I am not a psychiatrist, I see one and it took me reconizing I needed someone neutral to talk with about my problems that were affecting my everyday operations. I am not cured but Rome was not built in a day. Therapy is a process and simply getting someone to reconize they might have to ask for help. By the time I realized it I had ruined the relationship with the love of my life and a best friend. I said things that couldn't be taken back and now asking for help seems so small compared to what I lost. Be delicate because if they are showing sides on the outside then more than likely they are falling apart on the inside and maybe a slight suggestion or sending an anonymous letter with a business card, i you fear they will see it as an invasion of privacy. Remember they have to want to get help. You can only lead a horse to water but you can't make them drink. Best wishes!!!
