dont know what to think

hubby and i recently went away for the weekend for my bday. we recently went through a miscarriage and during the weekend i was talking about mental illness as i have been struggling with depression since losing our baby. hubby made a joke about me being in a straightjacket and i lost it. i started crying and we had a big fight...ive been feeling crazy lately anyways and this tipped me over the edge. what do i do??
