Do i have anxiety?

Hm i'm too emotional like i cry for the smallest things and i get super angry and snappy and over it very quickly... i worry about everything and i'm constantly making calculations of the money i'll make... i get headaches often and my emotions are very intense i feel them to the extreme... i also have trouble sleeping and i'm easily waken up... i always think my bf or someone is dead in jail when i can't get a hold of them... i'll feel like something is 'wrong' and i have to think to myself like exactly what it is that i'm worried about and then i realize that i wasn't even thinking about anything... but i'm pretty normal too i work, go to school, have friends, i like to party and be social i'm just a worry bug... but is worrying THAT much normal? i always think there's competition for my significant other... ahh i'm just crazy, but is this normal?
