When interacting with someone, it is important that you are yourself and do not feel the need to behave like someone else to be accepted by your crush. It is justified for you to feel self conscious around them. You may also feel like presenting yourself in the most impressive way you can think to, just in order to impress them. However, this is not recommended. You should try to be yourself to the best of your capabilities and your crush may accept or reject you for the way you are. In fact, they may even be more attracted to you if they see you being confident in your own skin.
