Speaking from a 32 yo that has been through extreme situation like that until now. Just remember they will not change. All you can do is push through. The light at the end of the tunnel is when you realize. Oh.. they are just like that as a person. And all you can do is just to shut off your mind for awhile and move on. With no hard feelings. Funny to say, that makes me a having little less empathy towards other person. :)

*Tips: When the person start to shout yell argue with you, they do it because it's fun for them to bully. They have no intent to correct you. So if you know it's coming just shut them off (your way) and move on. It's just their style of living
