Well, if you are talking to them, then it's better to just interrupt the conversation or quarrel and leave, I personally also live in such a family and my brother saved me before, and now he moved away from us and lives with his wife, well, the best option is to move out and cut all ties delete their numbers with them, etc. I personally have already gone crazy, I become a psycho and selfish and I don't give a damn about everything I skip school if my friends beat someone I'm with them and it would be better not to have such a family I wish good luck
Format communication to what is acceptable to you - show the boundaries of what is permissible for those around you and that going beyond these boundaries is punishable by interrupting communication. No offense - just interrupt the conversation and leave.
A new conversation begins in a normal way, before the permissible limit is crossed and again interruption, etc. Try it - two options as a result - or they will communicate with you in a format that is acceptable to you (if you are dear to others), or all communication will stop - if they are interested in you only as a vessel for draining negative energy (and they ceased to be).
And nothing, if you don't move out. To achieve something, you need to be ready to do something for it. If you wanted sympathy and cry, then this is it: you poor poor, how bad they are and how good you are, ayayay. And if the question is that you need to save yourself, then you need to do something for this and be ready to pay for it with something. Coexistence with nervous psychos will affect you all the same, whether you swear with them or ignore them, the general atmosphere will unnerve and turn into a nervous psycho. So there is only one way out - to move out. And if you do not move out, then cry and seek sympathy, but not ask for practical advice.
