My dad causes me so much stress, I really can't control the stress I feel anymore, I get really bed headaches and bodily pains, I cry so much, I really want to run away but I don't wantto hurt my mum?

I understand as stress from your dad is causing you to feel these sensations i understand completely as I have went through the same issue. You are not alone in this as you have others who can support you through this ordeal and be there for you when you need support. Try and speak to someone who can help you with this situation and help you manage your stress so you can deal a lot better when your dad annoys you about things. Stress can be managed by self caring and looking at books that can help you cope.
