How can I attract guys?

smile and laugh more

You need more confidence, confidence is attractive, no one finds self loathing! Confidence is something that comes from within ones self, its not really a personality trait. It comes with being happy with your self, I lacked in confidence most of my teenage life and due to an incident I re-evaluated my life and was able to sort my head out, accepting myself and becoming happy for the first time in years I must had. This in it’s self brought on new confidence. My main point is to become happy with your self and happy single, and to stop looking, once you do that, your attention is filled with other things which are more positive and some one will see this and approach you, this I can assure you of

Hope this helps and just to note your an attractive looking girl so just live life your young - what I have found is to stop caring it makes life so much easier and enjoyable.
