Is this depression, bipolar, mayber even a little normal?

i have horrible anger, sometimes not all of the time it may be like that for two weeks, more or less? anything can set me off, a simple question, misunderstanding, sometimes nothing at all i am just angry and i don't have a reason but so angry that i feel like i need to act out, like break something or yell. im 19 years old so i cant do these things just because i want to. my husband tells me that it is not normal and i notice some of the time and other times i feel the way that i feel is normal. i feel like i may be bipolar, i have looked into it and feel that some of those things apply to me and i have taken the tests online and every one has came back as bipolar. i have felt this way since i was about 14 and things have just gotten worse. sometimes i feel untouchable and perfect, others i feel low and depressed. i feel sad and down and others i am fun and energetic. i go from feeling happy and optimistic and other demanding love from my husband but enough is never really enough. usually i want to have sex everyday but there are times when i have very little interest in sex. sometimes i really do not want people around and others i am the life of the party. honestly i feel like two people at times, sometimes i feel like the way i am is normal but right after the change i can realize that there is something wrong with me and not everyone feels this way. today is a good day, yesterday was not the best but it by far wasn't the terrible like others. idk any advice or help, especially from people with mood disorders?
