I wanna die

Ok! I am seriosly getting severe withdrawl symptoms from the Effexor.  I almost literally beat up my own mother I am really starting to hate my self more and more.  I want to die my depression is getting worse and worse I was stuck at home in the bathroom crying my head off and I dont know why I was just crying uncontrollably.  I am now on celexa for depression but its not helping the withdrawl sympoms from the effexor.  I was about to take a knife to myself.
