It can be extremely difficult when the people around you are fighting! Do you have anywhere you can go to just escape sometimes and avoid it? I know from past expereince that sometimes it can help to just have a space where you don't have to worry about it all.

I would also suggest thinking about whether you are in a place where you can talk to them about how it is impacting on you. Often parents don't always realise the severe impact that their constant fighting can have on their kids as well.
