First, try to convince yourself that nobody is against you and that if they come out as too harsh, it is not intentionally. Twice so if you are dealing with people from cultures where communication is more direct or confrontation (not in the bad sense) is normal.
Then, if you are an employee, it helps to think that you already have been paid for the work being criticized. Sounds unrelated to the original problem, but for me it helps to dismiss a potential source of stress. Also related to the fact that you are not your work and it is not good to identify with it.
Also, think of the times when you might have come out as too abrasive to a colleague. Think how you would like you comments not to have been taken so harshly. Do the same with other's comments.
