I don't think that you would get laughed out of a therapist office. One thing to keep in mind about trauma is it doesn't matter what others think about what you experienced it only matters how it effected you. I don't think that bullying is a minor issue, I know from personal experience how it can effect your life.
I think that going to a therapist would be a good step, it might help how you feel.
