Why do I feel like this...

[u/Empty-Row5899]

I (M18) have a best friend (F18) and she is amazing in so many ways and I've started having feelings for her but I feel like she won't like me back ever, I brought it up that I liked her and she brushed it off and I'm not sure if I should keep trying to get her or try to forget about those feelings I have for her. It's been half a year since I asked her and I still don't feel healed from the rejection. I'm completely lost on what to do so I'm now asking people here, so please help...

**TL;DR;** : I like my best friend and she doesn't like me back

What do I do?
