Helping sorrow

[Minyatur]

How do you help people who are full of sorrow and cannot see light. I've been called multiple times in my life to help persons like that who are not good with themselves nor the world around them and I'm always clueless and powerless in my attempts to help.

Spend some time visualizing them in the happiest state you can imagine, and then take inspired action from that image.  

Then, you become a cooperative component to their happiness as opposed to their sadness.

That last part rings very true, it all seems about refining our intentions through the means that work best for us. I'm no very good at visualization but I can try something of the sort, hadn't thought of that.
