I feel this bud. You're not alone. Thought for me it's not normally that I think that others are better than me, I just think that I'm not good enough and other people are normal. And as for the crearivity thing...I mean, we are our own worst critics. But like...no idea is worthless, there is something out there for everyone, you have no idea what people will be drawn to. And even if you make or do something and it doesn't take off, it doesn't mean that it's bad it just means you didn't have the right audience. Or it's a learning experience, the idea might be good bur you're just not practiced in the execution, there's nothing wrong with that either. It's a learning experience then.

Well it's not true that you're worthless and stupid. It's something you feel but you have to do affirmations to help your mind. Because you're just as valuable as they are. Infact, you have to be way more valuable to yourself, to believe that you are more valuable, because you must be or else then what you believe, you make real and it isn't. That's why I'm a Christian bc the world teaches us the wrong ideas and from being a Christian, I learn to value my worth more and more.

If there is something you can do, like some skill such as dancing that you put value to and you can achieve then aim for that. Building more self confidence and self worth will be your best bet in my opinion.
