DEPRESSED!!!

i feel so depressed right now like nothing is going right....i am going through something i hope you never do!! a miscarrige it is one of the worse things there is,its like loosing a child who you will never get to know. its painful in so many ways rather you were trying or not. if you have a heart it makes you depressed!! it makes your mind wonder:what could i have done diffrent,is it my fault,can i get pregnant again and carry to full term,should i even bother trying again just to be hurt????? i know everyone has diffrent thoughts on miscarriges what is yours?
