Imposter syndrome

I always felt this when I was rewarded with good results. Because when I see somebody else work, they are so much better than me and I never feel like I deserved it. And when the opposite happen, I always said how come I didnt deserved to be recognise? I don’t think that my artwork is that bad. Is always the constent battling of the confliction within myself. It gave me such a pain in the arse feeling and I don’t know why I do it to myself? Do you sometimes feel the same?
