I feel really irritated and stressed I feel like I'm going to burst out and cry at any second I'm angry a lot, I'm always, just so confused What's wrong with me, and is it something I should tell an adult?

Yes you must talk to an adult.

Yes..you may be pleasantly surprised to find they too have probably felt the same way when they were your age. Most people have. There are many things that happens in the life of an adolescent.. Emotional, spiritual, hormonal plus the added stress of trying to find your way in a very complicated world. Reach out .. And hopefully you will gain some traction

Yes---talk to mom or dad or a school counselor.

I'm sure you are somewhat frustrated and could use some indipendent perspective on what's happening with you that could make you feel and act this way.
