Crying non stop

For the past few days I've been crying on and on . Between me not getting any sleep and being in pain constantly . And my doctors telling me one thing and then changing it to another . My stress levels are at an ultimate peak . I've just been feeling discouraged . Like I can't do this anymore. I literally have blisters under my eyes from crying so much . 
I don't want to hurt my baby but I seriously can't stop crying . Please help .
