I said you choose your brother who drinks with you, and go to relatives' house at some time or on holidays. The main thing is to let him prove that you are unintentional! Don't apologize yet. Let your friends treat your drunken gaffes as jokes when you are happy. You smile and apologize to your relatives. This will not only solve your depression, but also maintain your respect. And it will be done in a pleasant atmosphere! You should discuss the method of operation with your brother. Buy some good wine before you go ! ! Don't be too formal! ! ! Remember: make things clear in front of your relatives and don't repeat them. Just scratch the surface. Stop it! ! !
