That's a really good sign to go see a psychiatrist. I started having that problem a few months ago. I was just starting to figure out that something was wrong when someone finally told me how bad it was and how many people they knew were pissed. It took a few months to level off and now I'm starting to recover again. Be very discreet about who you choose to ask what they think might (if anything) be going on with you. It might even be best to get professional advice first before asking anyone. I don't know how old you are, so if you need to talk to your parents to get help, sooner would be better than later.
