Generally telling someone you like your feelings isn't the best way to go about starting a relationship. I know this is easier said than done. What you need to do is invite her to something fun you're doing that's not anything like the atmosphere of a date. If you're going to hang out with some friends at a bar/restaurant or go watch a sporting event, that's a great way to get her to go places and have fun with you somewhere. Most girls like being social, and if they are with you and having fun while being social with other people, she'll give you more of a chance. Right now, you have laid your cards on the table and there's nothing drawing her towards you because she already knows everything about how you feel towards her, so now you have to work extra hard to build an attraction and that's pretty much the only way to do so
