For the older ladies?

I'm 50 and I'm starting to go through menopause. I have terrible emotions and can't seem to control them. I've been awful to everyone around me. Yesterday I cried so hard. I've been taking anti-depressants for about 10 yrs. (nothing to do with menopause) So, can someone tell me if youre depressed to begin with the symptoms can worsen? PLEASE help. I feel like I'm losing my mind. I felt like I wanted to kill myself.
