It’s not black and white. PFS is a real and legitimate disease AND you can have problems with people in your social circle AND you can have pre existing issues.
It’s not like PFS only affects people with no pre existing issues or no social problems. Normally, diseases go the other way. When you are unhealthy or have unhealthy relationships, you’re more prone to additional diseases. There’s a lot of research on that.
But I always wonder why people care about those things. The fact and the matter is we have PFS. It doesn’t matter what’s in the past, where it comes from or whatever, the only things that matter is the present and how to deal with it.
