Here is a helpline I found that is not limited to helping teens:
The National Domestic Violence Hotline (NDVH) was established in 1996 as a component of the Violence Against Women Act (VAWA) passed by Congress, NDVH is a nonprofit organization that provides crisis intervention, information and referral to victims of domestic violence, perpetrators, friends and families. The 24/7 number is 1-800-799-SAFE (7233) or TTY 1-800-787-3224.
