Hey you!
I think you’re over analyzing the whole situation. There is no hint of desperation or neediness in your email and no way for her to assume anything other than what was implied. Dont worry! Im sure she will get back to you in her own time. She is probably busy. If you dont hear from her, drop her an email in a week or two. In the meantime keep your infatuation in check. The easiest way to do so is to assume she likes you back. When you assume she likes you, you will look confident. If you assume otherwise your actions will come off as desperate. Keep in mind neediness is a state of mind on a specific set of actions. Hope that helps! 🙂
