Depressed after my baby died of sids. Can you tell me how long I will continue feeling this way?

Mourning a child. Sorry to hear about your loss. Mourning can make a person unfunctional for a while. Usually it should last to three months then the person can function professionally and personally almost normally. In special case, the doctor can wait for up to six months before declaring severe depression then treat accordingly. Treatment can start well before the end of 3 months if too unfunctional.
