I understand....you're family is sending you insane and you need to live on your own.... and you're stressing out, I hope you don't go crazy in August, can you avoid being at home as much as you can until it's over? So you can avoid your family, Just think about how happy you will be when August is over and everything is hopefully sorted out and you don't have to be around your family, and you can leave that part of your life behind, then you can be yourself.
If you dislike being around them that much...well be grateful that you aren't them..if they're that bad, after all you can leave them behind, but they are stuck with themselves. (I'm not sure if anything I said made sense)
