I'm a 5w4 and when I was undergoing some rough patches especially last year, I appreciated my friends reaching out to me. While I still declined most of their invitations to meet up because I didn't have the wherewithal to get outside and interact with the world, I was comforted to know my close friends were available if I found myself in dire straits. I think it'd go a long way to let your friends know you're around if he/she is in a bind. I doubt a true 5w4 going through a tough spot would want anyone to 'fix' his/her problems or give out tons of advice, but simply letting your friend know you're around and care for him/her goes a long way - well, it does for me.
