You do deserve better. God i hate people who prey on other people. I think and hope there is a special ring of hell devoted to those type people.
There are better people out there. That said, how do we help you now.
If you have a choice of verbally abusive parents and a possibly sexually abusive boyfriend than my 2 cents is stay at home for a while till you can get things sorted. Try to operate at hours that your parents arnt around, if they are home during the day go to the local library or church, or hike, bike, if you can find a job you like, anything to get you out and from around them.
Verbal abuse is rough enough, you dont want to be sexually abused. Many men are looking for someone they can control and they will do bad things to you. At least if you are home you are basicly safe from that.
Take your time and get yourself settled. You need time to grieve for what you have lost, and time to deal with the reality of the new BP you. If you are having a problem with meds contact local doctors and ask for free supplies. Tell them what the issue is and that you are just trying to keep healthy and sane during this time that you are putting your life back together. If you have to half your med intake to strech them out longer. THis is an extreme measure, and is much harder but if you can get at least half of what you need it will help out more than you getting zero of what you need.
Good luck and keep posting here. We are here to help and listen.
