The cost of extreme privacy is your mental health and human relations. As rough as it sounds, you have to make a compromise, because you will not be an Edward Snowden in your life. What you can be, however, is an individual with a private life that beats out 95% people at having better privacy.
While I do not want to recommend it for privacy reasons, having just WhatsApp is good enough to strike that balance, to keep that one outlet open to society. I ended up doing that, since I realised barely a few people came to install Signal for me, even though I have a lot of leverage. They would instantly prefer normal calls and SMS over the usual WhatsApp, which is way worse for message content privacy and security. I did that experiment announcing reducing and even stopping WhatsApp usage, firewalling it and opening it weekly to check messages, and did gain a lot of leverage, but life became harder and stressed.
If you feel like you want to talk more, you can, whenever I will get time online. I can help you with threat modelling.
