<human>: We've (I'm 23, she's 24) been "dating" but not committed for 4 or 5 months. We've spoken about committing and figure it's something we see in the future, just not now, if any of that matters.

Basically I've fallen for her so hard that her moods affect my moods. The way she responds to my jokes, good or bad, decide whether I feel good about myself that day. If she's quiet and doesn't want to talk, my brain overclocks and can't focus on anything other than figuring out some way to make her smile.

It's not healthy, I know that. It might sound clingy or needy - I guess it _is_ but I don't _act_ clingy. It's just my thoughts that I need to get control over.

I want to be happy alone again. I don't want to be thinking about her _constantly_ when I'm not actively chatting to her. I want to be able to sit down and play a video game or watch a movie without thinking "would she be enjoying this movie?" or "I wonder what she's up to".

I'm in love - I know that. It's not a bad thing, but I need to stop letting my relationship with her affect my self esteem. What's the best way to go about doing that?

<bot>: The way things are going with my crush directly affects the way I feel about myself and I want to gain some control over my emotions. What's the best way to disconnect the two?
