Help I Love Someone I Cant Have And I Dont Know What To Do

So it goes like this, there's this girl who iv known for awhile now, we've always been friends and Ive always thought she was an amazing person, but every time I wanted to say to myself, 'I think I like her' my mind would just quickly force me to realise what a complete idiot I was being, because I know that there are better guys for her and I couldn't go out with her knowing that I didn't deserve her.
But now she has a boyfriend and I just can't manage my emotions any more, every time I see her or think about her my mind turns to mush and I can't think of anything other than daydreams about us together doing stuff like hugging or cuddling or talking, and honestly its driving me insane can anyone help me?
