Why does everything I do not seem to be good enough for anyone?

The first question you have to ask yourself is, are you doing all this to get validation from people? Or to make yourself better. When you think about this and get the answer to this question, I'm sure you'd begin to care less what others think, and you wouldn't stress over what people think. Nothing is ever good enough for anyone, breathe even parents. But you have to be comfortable in your own skin. Try to breathe, calm down, do the best you can do, and leave the rest. You always do not have to be a jack of all trade. I'm positive you would figure this out sooner than later.
