The feeling what you do isn't enough, that you're not good enough. Doubting your own abilities, thinking that way long enough, it's stressful. No matter what people tell you you always feel like you're inadequate, and you're scared that if you think you're amazing then you'll just be narcissistic. The feeling of trying to sit somewhere in the middle, trying not to come off as attention seeking, but trying not to come of as bragging. Getting stuck in that pocket of confusion takes a lot out of you. So, just take a moment to think. The only person's view of your expression that matters is your own, that's what they all say. All in all, just be confident in what you can do, with time and practice maybe you'll reach your own standards. Be happy with what you can accomplish at your best, try to push yourself farther, that's what matters. But you also have to know, you have to take a break every now and then, for me that's isolating myself and relaxing my mind. I'm so sorry this post became a rant.
