I feel angry when my husband takes advantage of my mental illness and lacks the empathey and compassion that I need to thrive in my life.
I feel useless
@BeingOfServicethat is just nonsense. You are very useful. You have purpose. You have been blessed with talents, gifts all contributable to humanity and it's well being.
When my best friend says everything is my fault.
I feel most angry when someone who is meant to understand, does not and those who do not know anything about what's going on talk like they know every thing when in actual sense, they know nothing and do not understand anything.
People I thought I trusted go against me
Someone I care about gets insulted for their differences from some random person
I feel most angry when I see someone being rude or unfair to another person 
lately I get most angry when I repeat the same mistakes in terms of the choices I make. I know better. I know they hurt me and my relationship. Yet I still do the same stupid things.
I just become infuriated when someone pretends to know my pain or tries to put themselves where I was when in reality they have no idea.
I feel angry when I feel stuck, like there is no way for me to move forward or to go anywhere. I guess I just hate feeling trapped.
