I can`t stand my relatives. Various cousins aunts, uncles, cousins of brothers, etc. But my family wants me to communicate with them. they constantly come to our house for holidays and just like that. I do not know what to do .. Do you think what I feel is normal? Maybe someone else also has this feeling? Please share. 
Try to have more tolerance, because it is family, we must have tolerance against that, but it is easy, you just have to become independent, have your own apartment that only among the people you want, that way you will not feel those things anymore. I think it's the best you can do, if you need to have your privacy always.
