i think all you need is a break to organise your mind. one can't keep blaming his bipolarity for every behavior he exhibits. people can be "normal" and still be aggressive at times. i have a colleague who asks me to go to the boss to see whether he needs anything fearing that he might be in a bad mood. you can't conclude that the boss must be bipolar. moods vary all the time but with BP it becomes clinically a disorder because it fluctuates more
My therapist has tought me that sometimes you are angry because you are afraid of something. Maybe you are worried about your meds not working yet?
I agree with the other comments. As long as you can avoid hurting someone (and words hurt people too) give yourself a break.
And remember, this is not your fault. It is an illness as real as cancer.
I hope you start feeling better soon.
what kind of medication are you on? don't beat yourself up over the anger.. i have days when someone simply says "hi" and I'm thinking 'what the hell is YOUR problem'... it can be a rough road, the whole bi-polar thing, but as long as you aren't physically hurting yourself or someone, take a breather... maybe talk therapy would help unravel the anger feelings?
It is OK to be angry, it is what you do with that anger is the question. If you are not hurting anyone then you need to give yourself a break. For myself when I am angry I ask myself what I am feeling guilty about, and I try to be gentle on myself....I know how hard that is when depressed.
Hang in there.
