The single best piece of advice I can offer young people currently in, and recently escaping environments of abuse is this:
If you at all possibly can, buy yourself a $10 prepaid cell phone at walmart and hide it. Give the number only to people you trust and keep your abusers completely unaware of it. If you can’t get one for yourself, get a friend to get it for you and smuggle it to you.
In a situation of abuse having a phone your abuser doesn’t know of and can’t cut off or take away can literally save your life.
And when you’re away from your abuser having a phone they can’t control or harass you over can save you a ton of emotional ache and worry.
Please, if you are being abused, find a way to get one of these phones.
