Worse emotional feeling

Been thinking through lately, and I realise and felt, this was the worse feeling that I hated the most. its a feeling of loving someone, but you could't tell her because you're afraid of the consequences. But, if you don't convey your feelings, here is another feeling that is like shit. You'll feel this feeling being bottled up inside of you, you feel so much love towards her, you want her to realise how much feelings you have for her now. She is running round in circles in your mind. Get my point?? So what should you do then?? I feel its like flipping a coin, you either try out your luck or you can just stay there and be stagnant. The last option would be telling yourself to forget about it and just move on in life. But its gonna be a very hard process. And guess what? This is happening to me now and I'm in a dilemma. I just wish that I would get what I wanted.
