Anyone else feel like this?

Has anyone else ever had this problem? I used to be really emotional (the typical angry 13 year old but worse) and cry all the time, but over the past four years I've learned to control it and everything. The only problem is, I haven't cried at all in two years!
My grandpa died and I didn't shed a tear-although that isn't too weird, I didn't even really feel anything-I get really pissed off at my brothers (like just now), but then I just settle down in a few seconds. Even when I'm really excited, I get over it in a few minutes. This might seem like a good thing to some people, but I hate it! I really want to feel emotions! I think these things for a long time, but I never get the anger, rage, sadness, anything!

If anyone else has had this problem, and there's any advice you could give me, please do.

never than bad...

I have been really emotional...then I couldnt cry for a while and not im sort of in between, sometimes really emotional and then I cant cry.

Maybe you just found other ways to manage your emotions.

well, yeah, I do manage them in other ways, but they go away so fast! I want to feel emotions adn cry and stuff!

Sounds like you're suffering from supression. Your feelings are being supressed for some reason.
Maybe this is caused by depression?
If you feel really low, your mind can sometimes de-stress itself by numbing emotions.

I really suggest seeing a doctor, who may advise a councillor?
