<human>: Not sure if this belongs in this subreddit or not. Let me know and I can move it to a more appropriate place if need be.

Here's my issue:
Over the past year, I've noticed that my brain doesn't work in the way it used to. And not in a good way. I don't care about people the way I used to. I don't enjoy the hobbies that I used to want to devote my life to. Where my brain before was always buzzing with ideas and thoughts, now it feels empty. I don't feel depressed (because I've heard that depression can cause your brain to work this way), but I also don't feel much of anything anymore, emotionally.

Specific examples:
1) I love/d writing a lot. I'd constantly be writing stories and poems or just be scribbling away in my journal. Since the beginning of last year, though, I haven't written much of anything. It's not that I suddenly dislike writing, it's just that my brain went dead and it feels like I have nothing to say.

2) I have an awesome boyfriend who clearly cares about me a lot. I'm very, very happy with the relationship and we've been together 9 months (meaning that we got together just as I was starting brain shut down mode). But while I do love him, I don't feel towards him the same sort of "I like you feelings" as I had with guys in the past and I'm decently sure it's affecting our sex life (I can't get aroused enough so sex ends up hurting a lot for me). 

At first I thought maybe I should get out of the relationship because I didn't have those feelings toward him. Then I realized that things that normally turn me on don't anymore. So maybe the cliche "It's not you, it's me" is coming to fruition?

Can you condense the text into three sentences or less?
<bot>: I don't like things that I used to like and my brain feels dead.  What the hell is going on? I'm 20F if that makes a difference.
