Emotional breakdown

Due to the fact that the lady is now encountering, she is suffering for emotional breakdown. She cannot help herself, she wants to help but then she thinks that she can’t do it without that man. Every night she always thinking about that man and she use to cry hard but nobody knows about that except her friend. She cannot accept that they were separated without any reason at all. This lady always asking, what is the meaning of love? How about the true happiness of love? Is this kind of emotional breakdown is part of that love? Can that lady do something about it in order for her to escape to that breakdown? How can she avoid that man in this case? Why is it if there's a love there's always pain? Where is the happiness? For me, it is really hard to fall in love. You have to be ready in all aspects when it comes to love, because you will never know what will happen to you in the future.
