Shots and Bitchy Moods

So it seems lately I've been pissing everyone off and I've figured out the reason why. In June I got the Depo shot. For those of you who have no idea what that is, it's a birth control shot. I was told there would be almost no pain during my periods and my periods may stop existing. Well god I must have the worst luck and side effects because of some unholy reason I've had my period for over a month. They've been really light, but also I'm pretty sure this shit isn't supposed to happen. Also the pain is still there. My mood has been complete shit as well and I've been taking it out on everyone. Every small thing seems to piss me the fuck off to the point of me losing a good amount of friends. The shot wasn't even due to me being active. It was due to painful, heavy periods. I have to say, I'm never doing this again. Oh and I'm also constantly puking my guts out. The only form of birth control that actually didn't suck ass is the patch, but no one gives that out anymore due to it having too many negative side effects or something. When I was on the pill I was constantly puking, crying, and I passed out and fell down the stairs spraining my ankle. The shot seems to work better on my autistic cousin, but I guess it could be messing with my current medication. People wonder why I'm in such a pissy mood. You'd be pissy too if you were bleeding for over a month.
