Birth control pill and drive etc.?

Well I'm 17 and I've been on the birth control pill for 3 months to regulate my periods but I've had a bunch of side effects. It's making me really sappy and emotional, I find myself always wanting to read romance novels, watch romantic movies and cry to sappy ballads which is REALLY a change of character for me, I was the type to watch horror movies and listen to punk music. Also I am constantly . I mean constantly. I'm sorry to be graphic but I can feel that my oris is always extremely hard and I'm always aware of it, which makes it difficult to focus in cl or on anything else. I try to think about old shoes or dog crap but no matter what I'm thinking about it doesn't change and there's always alot of sensation down there. And if on top of that I come across anything I find y it just is unbearable. I try to masturbate to relieve it but it doesn't work no matter how many times I do it, and it's not uncommon for me to do it 5 times a day. Maybe to others this sounds like some great thing but honestly it's a little much. I'm also having a hard time sleeping, sometimes feeling alert after not sleeping for 2 days and I find that my hands get the shakes especially at night. I also experience random waves of heat throughout my body. So all in all this pill is messing me right up but my periods are very regular. What a trade off huh? What I'm wondering is will this keep going, are these normal symptoms and has anyone else experienced it? Might everything settle down after I've been on it for longer? And how do I know, if I go on another birth control pill, that I won't have another slew of crazy symptoms? Because I really would rather have irregular periods than go through these extreme changes over and over again. Thanks for any input.
