Criticism can be both a blessing and a curse as it exposes your work from the vacuum of your own mind to the thoughts and ideas of the rest of the world.
The biggest reason that authors struggle with criticism is that our writing is an extension of ourselves and we have a tendency to take any positive or negative comment and apply it to ourselves.
Here are a few tips that could help you cope with feedback.
1) Though important, take feedback with a grain of salt. Everyone has their own opinion of writing just like art. If you feel the feedback is just taste, then you can safely move on.
2) If the feedback has points, consider them. Our profession is unending and we are always learning. Your commenter may have some valuable insight that you would have never considered.
3) Ignore the trolls. This is, after all, the internet. There are people who take great pleasure in attacking people for the sake of attacking. If their review is unfair and you can respond, do so in a calm manner. The response is not for the troll but for the future readers that might stumble on your work.
Above all, remember, if you like your work, that is the most important part. It is good to take your reader's thoughts in mind as they are paying customers in the indie world but the integrity of the work is yours.
