If you are legally "competent" - at 18 you are probably legally emancipated in your state. You can leave home (if physically/mentally capable) but without any signs of physical abuse, I doubt that your grounds for suit are valid.
a teacher does not have to take any abuse of any kind from any parent. The teacher can call the principal and let the principal deal with the situation.
Emotional
Depends on how traumatic the emotional abuse is.
Yep
Not on a general basis, but if one partner wants to get a divorce from the other they can use 'emotional abuse' as a way to get that divorce. If one is emotionally abused, it is just as bad as being physically abused (you just can't see the scars) and the victim should leave their abuser.
Any form of emotional, verbal, physical, sexual, and neglect.
Yes.
Sexual assault, physical attacks, verbal, psychological and emotional abuse
You can't be HURTFUL and not abuse. Abuse can be verbal, emotional & mental. Talk to someone about it. Perhaps a school counselor or priest.
No, it isn't right if a parent verbally abuses a child.
Sexual assault, physical attacks, verbal, psychological and emotional abuse
Abuse.
