No, I'm sorry, this is flat-out retarded. USE SOMETHING ELSE OR SUFFER THE CONSEQUENCES. https://element.io/ implements the matrix protocol. It offers all the features you expect but supports a federated, privacy-oriented infra. If your mental health - yes, your mental health may hinge on your ability to contact people for work or for studying - hinges on being able to communicate, then maybe have a secondary channel for communicating? Using facebooks services is a vote of confidence in facebook. You don't get to complain when it turns out that you misplaced that confidence.
