Anxiety has a big impact on my life, so it stops me in a lot of things, but it’s mostly when it comes to talking to people. For creating things, I have this feeling of it’s not gunna be good enough so I don’t do it, but for some reason my brain kind of made an exception for crochet x)
But if it was about writing fiction like you, then I would definitely feel the same. I think it’s a very common thing to feel. It happens a lot that when I watch an interview of a popular author or movie director (or in any creative field), I love what they make and I think that they are a very confident person to have come this far, but they end up saying they are very scared to disappoint people, and have to fight this feeling of being illegitimate. But if everyone was letting their fears stop them, not many things would end up being created.
I think you should do whatever you feel like doing. I guess it’s not for no reason you started, so if you enjoy it, just do it. If people liked what you previously made, it obviously means you can do it good. I think if only a few people like what I make, it’s already a victory. I guess it can be very hard to receive negative opinions, especially if you worked hard on it, but in fact they are just opinions, and as people have various tastes, there will always be people who like it and people who don’t like it. We are all unperfect humans. Maybe it’s better to concentrate on people who liked it, and use negative reviews to improve (if they are pertinent of course).
I think we also tend to take it too seriously. Art is for fun, there is no big responsibilities. You are not a doctor, having people’s life on your shoulders, or anything like that (well I don’t know, maybe you are ^^'). If you fail, then people will just go and read something else. They could be disappointed, and so what ? It’s nothing dramatic. They could be disappointed in one thing you did, and love another thing you did. Your job is to create, and if you have done the best in your point of view, and had fun making it, this is great, and this is enough. Give what you have if you feel like doing so, and what happens next is never a serious risk. It is okay to fail. If people don’t like it, if it has flaws, or if they’re just not receptive to it, it’s okay. It’s the “risk” of this job, and I guess we all have to accept this aspect of it in order to create something.
