Is it normal that i get angry at my boyfriend so easily?

Learn to forgive and forget, the bullies are in the past, don't carry their torment around with you in the present.

Being bullied and such as you were I am not surprised you are easily angered when such things as jokes directed towards you make you angry. It also seems that you don't want pity or anything like that. This is normal and to help curb your anger you should channel it into something. Some people use art and others video games emotions especially anger are very powerful and hard to control but also one of the easiest to express. The only problem being that finding a positive way to channel or express your anger is difficult. If it persists I would recommend finding professional help or discussing the bullying with someone you are comfortable with but will not pity you.

I have also been the victim of a lot of bullying and I can relate to you. In my case, I am not very angry, I constantly feel like I am inferior to others and I battle this feeling everyday.
Here is some advice from someone who can understand how you feel. There is no solution for an overnight "fix". What you will have to do is constantly tell yourself to move on. You have to start small. If here are little things that your boyfriend does that make you mad, then you have to ignore it. Even if that means forcing yourself, leaving the room, etc.
It is going to be hard because both of our problems are something that is now engraved into our personality. It might even take years to change how you react to things, but if you want to see results then this is how it has to be done.
I am still in the process of trying to become more confident in myself, but its hard. It is something that I have to remind myself about everyday. I have a significant other as well, so I really need to try hard. If anything happens and she really needs me, then I need to be confident so I that I can protect her.
I just hope you read this and understand what I am trying to say because I really don't have a way with words. Just try to keep everything in control everyday. Don't let it bring stress into your relationship and be strong.

I have a background of being bullied too.
That and my ADHD makes me grumpy at many silly things.
I doubt i can ever truly stop acting like this but with my boyfriend i start of by saying: I'm sorry, i can't help it but i'm furious at you for *Insert nonsense reason*
I'm transparent as water, otherwise i'd never tell him when i get mad and KNOW that i really don't have a reason too.

Be careful, you might end up scaring him off.

If you can, you might benefit from taking a step back when you get angry and reassessing the situation. Most importantly, you must breathe! Take a minute to think it over from every angle (while breathing) - the person who you are angry with, why you are angry with them, and if it is actually worth the energy of your anger. Not every person is out to hurt you! It's also quite important that you surround yourself with people who generally care for your well being. You already know you are naturally defensive in those kinds of situations you mentioned - and that's really excellent, a good start! Now you've just got to retrain yourself to take a minute and really think things through before you say/do something you might regret by lashing out in anger. It's not easy, because it's now a reflex to you....but I think you can overcome this. :)

People with anxiety disorder tend to avoid confrontation and displays of anger.

Maybe, it annoys you that he doesn't feel the same frustration as you and you want him to understand
