How do i move on from here ?

A price of me has died with my baby... I can't believe that this is happening in my life, what did I do wrong? I really don't know the right way to deal with this.  I'm drowning myself on the inside to be strong on the outside is so hard lately I'm not the one to wear my feelings but after all of this there is no holding back I am a train wreck even my job is to much for me I don't think I will ever be the same after this.
