<human>: She is the Greatest Person I have ever met in my entire Life and this is what breaks my Heart. She is in a serious Relationship with a good Friend of mine so I can't tell her and because Iam afraid how she reacts but if I don't tell her I'm not sure how long I can keep this up. Everytime she hugs me or our hands touch my damn heart flips and I can't tell her. 

What am I supposed to do here ?

I never thought I would ever end up in this kind of Situation. Reddit please this one time I really really need your help. I need an Opinion that tells me the cold truth even if I don't like it because I'm afraid I can't think clearly because of her.

I never thought I'll love someone again after I broke up with my first Girlfriend. Then it happens and of course it is the One Girl that I can't reach. 

I hate myself so much right now. Iam very desperate for advice here..
