Anna & Reign: To get out of a fandom, you have to realize that you have to grow up and move on from that "phase". It depends. Maybe she's the unhealthy fangirl, not an unhealthy fandom. If she doesn't get out, just let her be, it's what makes her happy. The fandom will die eventually. When it comes to a point that she's hurting other people by say, annoying them to death, that is when you have to tell her to calm down. Although she won't be out of the fandom, at least she won't be hurting anyone.
"All my friends started watching this TV series and I seriously can't relate to anything they talk about. What do I do???"
Anna & Reign: If you don't like it, don't force yourself to watch the show. Speak up about your uncomfortableness. Don't hate. I'm pretty sure you can talk about other things too. Maybe you haven't really realized why they liked it in the first place. Try it out! Maybe you'll end up liking it.
"Lately, I noticed that all of my friends are talking about the boys in their lives and no one else. It's fucking annoying."
Anna & Reign: Well, hormones. It's that stage of life. If you didn't know, in a woman's life, there will be a stage wherein a man is all she could think of; due to the fact that in the adolescent stage, we are developing certain hormones that affect our behavior towards the opposite sex. Well, you will also be like this. So for now, just listen to them; sympathize with them. You'll get there too.
