All I can say is that things WILL smooth over. It may take a while, but family bonds are stronger than you think. My sister went out with a total arsehole once. He was just wrong, but he had a way of making people like him - a kind of charm hiding some unpleasantness. She wanted me to lie on her behalf to him a couple of times, and I refused believing that if there’s a problem it needed sorting out. That caused some friction between us, but at the end of the episode I think she saw that my reasoning was right, even though at the time she didn’t and thought I was being unreasonable.
So, deep breath. Count to ten. As others have suggested, a couple of weeks away from it all will do you some good. Can you and yours grab a tent or get a YHA card and go on an adventure for a week or so? Distance may be a good thing right this moment. There is clearly tension, and it sounds as if you need to get out of the situation for your sake. There are times when you have to be selfish. It sounds like now may be one of those times.
The situation sounds like it is growing beyond your abilities to comprehend it, and I can quite understand your anger. However, I would say that you need to bite your lip more - making a bad situation worse is not your job, and ideally you need to rise above the mess and show that you are better than they are. Maybe you need to sound off to someone outside your family - get your own thoughts in order. Maybe a talk with a group like the Samaritans (
http://www.samaritans.org/) could help? I’d encourage you to try that - speak to your significant other about this too - he sounds supportive but I’m sure there is only so much of this he can take, and I’d reckon he’d back you up on this. We can do what we can here, but none of us are (known to be) counsellors (there may be some here but they are keeping quiet about it) and there is nothing like a conversation with another voice. Asking for help is not a weakness, and you’ve already done it once by starting this thread.
Keep posting here - you need a safety valve and if this is it, so be it. Just remember that there are other options available to you too. Above all, rise above it and do the things you usually do.
