A sensitive situation.

What is the best way to tell someone you love that they need to go to therapy? I love this girl but it's tearing me up inside to see her going through a rough time. I want to help her but I am not properly equipped to do so. She tried therapy before in the past, but stopped. I really think she should start again before anything bad happens to her. But I don't want to just go and say "hey you need therapy". How should I tell her?
