Do I have anger management?

I get very angry at the most littlest and dumbest things. Yesterday, I got mad cause my mom kept taking my flat iron out my room and using it in her room. So mad that I started cursing angrily to myself in my room and I kept spazzing out on everyone who was in my way. Sometimes, when I don't have things my way, I may even cry tears of angriness and frustration. There are much more pointless things that I get angry at. I don't think its healthy for me. I'm a 15 y/o in highschool, btw. Help, Please? :/
