2) Set boundaries and communicate your needs. If you are being offended often by the same person you might want to ask yourself why you are allowing this behavior. Technically speaking, people can't DO things to you unless you ALLOW them to. We teach people how to treat us and so if someone is constantly offending you, you might want to start communicating your boundaries and your needs. This particular person is showing you that it's time to start standing up for yourself.
3) Confront the situation. It isn't necessary to confront the person who offended you, however, if you feel like you absolutely need to do this then follow your gut. The best way to confront someone whom you believe has offended you is to prepare your discussion in advance using 'I' words. For example, "I felt really hurt when you said...". In addition, before you confront the situation, set a positive intention; set the intention that the discussion will go well for everyone involved.
4) Self-Reflect. Sometimes when we're offended by someone it's because they've hit a trigger button. Is it true that someone offended you or did they just unknowingly pour salt in an old wound that you haven't healed yet? Sometimes people say things or do things that wouldn't normally be offensive and yet, because we have an old wound that we've never dealt with, we feel terribly hurt or offended. In this case, it probably isn't about them so much as it is about you, but you are the only person who can discern that. Be real with yourself about it and if it is a trigger, you will want to deal that old wound once and for all otherwise it will just keep showing up in your life over and over again until you do.
5) Write about it. If you are offended and you just can't seem to shake it, you may want to write about it. Sometimes we have to get our feelings off our chest and yet we don't want to tell anyone about it. Writing is one of the best ways to deal with our feelings because it's something we can do on our own and we can write all of our ugly thoughts without having to feel bad about them. Get your feelings out no matter how ugly they are and when you're done tear up the paper or burn it.
6) Ask for Divine guidance. There are some situations that bother us so much that no matter what we do nothing feels better. If this is the case you can always count on your Higher Power. Ask that your situation be taken from you and healed in the most positive way for all involved. Once you've asked for help, get out of the way and let go and let God. This is when the real magic happens.
