You couldn’t feel that way if you had no doubt or did not care about your level or worth as a developer. So you do care about how others perceive your level and you are not totally convinced that your self evaluation is right.

I would say don’t judge yourself too much. You don’t have to be perfect (especially if you are not, and nobody is). You probably are in this business to learn, so give yourself some room to learn a bit (or a lot!) more. People that criticize your work may be wrong. Don’t take their criticisms as absolute truth. In case you feel they may be right, drop your ideas right away, ruthlessly steal theirs and make them yours. This is how you don’t get stuck in local minima. You don’t have to care about having been wrong, there are more constructive things to do.
