Physical & Emotional Abuse Support Group
Abuse is a general term for the treatment of someone that causes some kind of harm (to the abused person, to the abusers themselves, or to someone else) that is unlawful or wrongful. No one deserves abuse, period. Abuse can be emotional, physical, or sexual.
I can tell you first hand that being around any kind of yelling or potential for physical violence makes me want to leave, be quiet, or sometimes hide. I can't sit there and face it, or even yell back. My mind drifts, and I just want it to be over. I don't even want to defend myself, because I don't even understand what I am defending myself against. I just want to leave. And it makes me timid around other people. I usually can't eat, can't concentrate, can't relax. I'm facing a huge dose of that right now.
I certainly hope the best for your situation, and I recommend talking to a professional therapist, or just venting and asking questions here. You need an outlet and support.
Take care.
