I thought I had depression, but I'm not always depressed. My mood changes so much.

My boyfriend calls me bipolar since I'm really happy or I'm really sad or mad. When I'm mad, I usually break things. I've broken so many cell phones since they're always with me and my parents get mad over it since i'm wasting money and they don't want to deal with it, which only makes me more mad.

I have mood swings all the time and I can never controll them. Sometimes even I cry for like 5 minutes and get really hard on myself about things then I'll laugh and then I'll be fine.

Any suggestions?
