2. Discuss the situation with your close colleagues:

If you discuss about your problem with your colleagues whom you trust they can be of some good help to you. Ask them about, till what extent they were harmed by the same person if they were; enquire about how they handled the situation and in what ways they were helpless etc. So, if you collect some of the relevant information from your colleagues, it might be of help for you at some point of time.

3. Discuss it with the boss:

Discussing the problems with your boss directly will be more helpful for you. If you discuss your issues with your boss, he or she will be aware of the problem that you are going through. But while discussing it with them, your talk must not be in a way of complaining, instead a casual way of conversation will be good. Your discussion with the boss must be in a way of finding out a solution to the problem rather than just complaining like a high school kid.
