Mental Breakdowns

I never really seen anyone had any mental breakdowns or experience it before (I think)untill Today. A friend of mine cryed today i was actually not sure AT ALL what to say soo you know what i say, JUST PUT A BIGGGG SMILE AND FORGET ABOUT IT AND RELAX!! thats what i usually do when anything happens. Thats was all i could do to help out well u know what people say A FRIEND IN NEED IS A FRIEND INDEED!! I always help out friends whenever i can but sometimes its diffcult to help ALL of your friends because your very busy and all. I always try to be a VERY HELPFUL friend in ANY WAY I CAN NOT MATTER WHAT!
