I like your additions to your profile and I don’t think your purpose is too long. The first sentence is your purpose – and your second sentence summarizes how you want to fulfil it – that’s absolutely fine.
You may want to think about “help their kids better” – as this is quite generic. I sense that perhaps parents like Sharon want to help their children to lead a more fulfilling life?
I like Helga’s suggestion. When Sharon feels better herself, she can help her Yair better, too?
