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.
In a way, it makes sense that you'd feel this loss of identity, anger, and depression. While in the relationship you're in survival mode, you are in coping mode, the get-through-the-day mode. Now that the threat is gone you are processing through layers of emotions. All of it is completely normal and can be worked through with patience and perseverance.
