I’m still in favor of talking to your friends and family about it.
Just choose the words you use a little, depending on how spiritually open they are. Honestly, most of us just have to use the words “soulmate” instead of twin flame and that’s enough for them to kind of understand. Kind of is as good as it gets, but it means you can lean on your support system. They’ll not 100% understand but they’ll still want to be there for you, let them.
The twin flame experience sits outside the conventional understanding of relationships. It can make you feel like you’re losing touch with reality when you’re actually touching something deeper. The isolation phase seems to be really common though. A lot of us go through extended periods of loneliness during separation. It sucks but it also lets us go inward to reflect.
Places like this help a lot. At least here you don’t have to pretend or translate.
