For all we know aproudbyg is actually aproudstalker trying to get in touch with an unsuspecting online friend. We have very little way of knowing such things and therefore err on the side of caution and don’t give out personal info. That’s just the way it is in this crazy world we live in.
As for what to do, you can try to discuss whatever can be discussed publicly in the threads. Privately, you should try to find a friend and/or mentor to help you with the situation. If your friends have all dumped you because of it then they don’t sound like they were ever such great friends to begin with. Look for a Rabbi/Rebbitze or Kollel couple to be your mentors. There are plenty of caring people out there.
To anybody who haas friends going through similar situations: We live in a very confusing world and most people just need their friends to be their friends no matter what the situation might be. Do your best to continue being their friends and treat them the same way you used to (it is hard but try). Over time the “issues” will come up and you can speak about them, but don’t treat the person like this issue is their whole being: they are still regular people like they always were and would like to be treated that way.
