Drowning in my own pain !

I can't take it .. I feel so alone , my baby no longer has a father he's a grimy cheating bastard . I feel like I cry every second of the day , at school on break , before I sleep , when I wake up I can't stop thinking about what he did .. 
I feel like a failure , I feel like I can't breath like I just want to crawl into a ball and never come out
