Just a tip, but don't post pictures of people on the internet if they haven't given consent... I can't imagine you asked this girl if you could post her picture, and I really can't imagine she'd be okay with it! Stop posting pictures of her without consent would be a good start, and from there just talk to her and make your feelings known4THIS IS NOT RELEVANT ANYMORE

First of all don't obsess over someone so much that you loose your mind.
Be confident, real and ask her out, let her know about your feelings towards her and understand hers. If she rejects, gently tell her it's fine and end it right there and move on.0THIS IS NOT RELEVANT ANYMORE
