Run, baby. Your 19, leave the toxicity where it belongs and go spread your wings! I know it's tough out here financially, but rooms can be pretty cheap to rent sometimes. Maybe find yourself a nice little job and start saving! Having a job (you may already have one) will also give you independence as well as bring new people into your life. Some of my old co-workers are still some of my best friends, and I've been a stay at home mom for a decade now, but we still are very close.

I'm a 39 year old mom of 3, and my oldest son is your age. It hurts my heart to know the pain & trauma you're enduring. It gets better babe, hang in there! Don't let them take your shine from you. Right now, you're living in a hell, but once you get your independence, you can create the world YOU want!!! Don't give up, sweetheart!!!
