I think it just needs to feel good. You need to get it out of yourself because it deeply inspires and thus motivates you. You need to enjoy the process of it all (or at least most of it), not just aim for anything to prove others what you're capable of. I love drawing for the sake of drawing. When I get into it, it just gets me a little brighter, a little softer. I love inventing as I go, letting my mind wander on each detail that needs to be added just because it feels right. I love how everything is possible when I draw, and that I get to choose how every piece brought together makes sense as a whole by myself, as it comes from my mind and heart. I have a deep love for light and colors, for the construction of something that comes from all my observations and wanderings, every experience I have been inconsciously or consciously inspired by. I also love singing. I love connecting with the voice of someone, feeling like I am hitting the right chords, remembering some notes or lyrics that have stroke me with deep feelings, listening and singing to it, expecting and getting to the special parts once again. And I love dancing. When I do it, I feel like I am at my happiest, because there is no pressure whatsoever from anybody, I do not care that you like it or not, I love it because it is exactly what my definition of freedom feels like. If you are doing everything because of wanting to be skilled at it, it means you are always working and never resting. And that is never a good thing in itself. Give yourself a break, experiment and take some time to appreciate again the tiny littles things you've always loved in everything (be it from movies, books, music, friends, anything from the real world that has made you bright at some point).
It feels nice to get positive emotions from other people, but when you get too much into it, you are actually addicted to the feeling of manipulating reality to make other objects bright, so as to make yourself bright. And manipulation of anything is not pure freedom of being. It's living through someone else instead of nurturing your own unique and inner self. It never works that much and kind of feels empty, after a while. Of course, it is always a great thing to enjoy what you are doing, to be proud of it, and thus of wanting to show it to the people you love, or to the world. But that should always also come from a place of love and passion, so as to be sure to do it to take care of your own path in life. Do not surrender on your freedom of exploration for the sake of pleasing anyone. There is way too much to see and experiment for you to be missing out on anything that might resonate with you.
Do not worry though, we are performers, we love showing off a little bit, and sometimes it gets ahead of ourselves for a little while! Try to have fun and to re-connect with what you love, with friends you care about and I assure you it will come back, even if it takes a bit of time.
