Do you know someone who is struggling with depression or????

Here are some suggestions for helping someone that is struggling with mental health problems. 
One of the best things to do is to listen.  Listen deeply, with your whole self.  If you don't know how to respond, just listen.  Do not tell stories of your struggles or offer advice.  They have probably already considered many options.  The person that is talking is offering you some of themselves.  They trust you to be there for them.  Just do that, LISTEN. 
Follow their lead.  If they feel like joking around, then do that.  If the conversation is deep and dark try to follow.  If the conversation is too much of the dark stuff, step out of the conversation and take care of yourself.  If the person is talking about hurting themselves or others, find some help. 
Many times when people are stuck in grief, they have a hard time reaching out to others.  Offer them some specific actions.  Say you will meet them for coffee on a certain day.  Or that you will meet them for food or take out.  This offer is good since the person that is struggling doesn't want to ask for too much or too often.

Offer them LENS neurofeedback.  It can help the brain to calm down and work at it's best.
