I would ask “who hurt you?” but solitude can be damaging for one’s mental health too. No, seriously, I get the point you want to make but not having talked to any other person for 4 years is not healthy either. It looks like you have internalized a lot of these things that you wrote about and the way you talk about them doesn’t look like you can find whatever you need too.
You will need to start creating accounts in the apps/services you want with the traditional way of setting email+password. Not by clicking “login with google”
