The key to overcoming any problem is to become aware of it. The first thing to do is reassess how you deal with conflict (via Psychology Today). If you tend to keep things in more than most people you know, especially if you don't communicate your needs or when something is bothering you, that is a problem.

It can be difficult for many to realize this because often, people who have a fear of conflict have spent a lifetime avoiding it, so it seems normal to them. However, if you get a sense of having to stuff your feelings, that's a signal you're not dealing head-on with an issue.

As you go through your week, pay close attention when things disturb you and ask yourself if you are numbing out the bad feeling or avoiding it. That is the first step. It also helps to chronicle situations where you think you may have been quieter than you should have been, as well as how you felt at the time.
