I am so very sorry that you are going through this.
Do you enjoy reading? When I used to live at home, I didn't get along with my family very well and often delved into the world of books. It may not help the headaches, but it may provide an escape.
As for the headaches, I find that lavender scented things help.
You're so sweet!! I've been trying to read more and it's helped. My only real answer though is to move out. Guess I should start saving.
