I think most, if not all of us, feel the same way at some point or another. It's part of being creative - whether we're writers, artists, actors, musicians, dancers... everyone who digs deep inside themselves for something truthful or vulnerable or difficult or precious or painful and then, rather than hiding it away, displays it to the world and asks if it has value (not necessarily monetary).
It's a terribly exposing thing to do. And rejection always hurts. But I think we have to teach ourselves not to take it personally (harder to do than to say!). And, when all is said and done, although it's wonderful when someone else likes our offerings, the only people we should really be trying so hard to please are perhaps our worst critics of all... ourselves. 😄
Write what you like, when you like, as often as you like... just to please yourself. Read lots, always remembering that even those writers whose work you love have had their self-doubts and bleak moments, not to mention rejections, and try not to comapre yourself to them. Those moments when you want to throw it all away always pass. And there'll be another story to tell tomorrow.
And if not, there's usually a sympathetic shoulder or two here! 😊
