Ever since I started the depo shot I have been angry at everyone and everything and I didn't see it at first, But I really started to notice after 5 months.. I didn't care that I was being mean. But I have to control myself... Changing to the depo shot was the second time I changed a birth control. I have to be on it because I have Mittelschmerz syndrome. Ik every one is different on birth control but does someone have their emotions it as excessive as I do??
