Reverse anger issues

Why can't I feel anger towards people? For example, if someone harms me or heartbreak me, why don't I feel anger towards them being mean to me?

Context: I'm very empathetic; I tend to help friends and family as soon I'm available, and I'm always very aware of myself, auto-criticizing my behavior. I'm also an anxious person.

Is anyone here like that? Do you know someone like that? Is it good or bad?

Sometimes, I feel my life would be easier if I could be angry at someone who was mean to me or did something that hurt me, but I'm not like that.
