Hey, just try to focus on your studies first, alright? I know it is easier said than done, because I also have a crush right now, and I am also unsure if he even likes me back or not. But I'm trying not to think too much about it and just appreciate the things that I have now. So, just try ok? You are still so young, there will be many many chances ahead. These kind of relationships stuff is very complicated, it drains your mood and your energy. It is kind of draining me as well, but life has to go on!! Don't let this one person stop you from shining! Just try to go with the flow ok, don't try too hard on him, don't put too much effort on him, and forget yourself. Remember to take care of yourself first.
