Are you absolutely positive that people can tell that your anxious or that your freaking out? You'd be surprised how naive people can be sometimes. It is completely normal to be anxious around someone you like. Even if you don't like LIKE them because maybe you don't want to give them the wrong idea. Right now it may seem like you can't be the lovey dovey type but you will when you meet the right guy, especially when he feels the same about you. Btw, good job for expressing your true feelings to that guy you like. There are many people who can't do that(including me) even though you had to fight with yourself. It's completely normal and it sounds like you handled it well.
