After patiently reading your question, I probably smoothed my mind. But I don't think this is a knot worth remembering. In my opinion, you should start with your own analysis.

First of all, you also said that you are an introvert, maybe a little withdrawn, and occasionally you will be left out by others. From your story, you can also see some of your personality characteristics.

There is a long section in the middle, which is very contradictory. However, this roommate didn't do anything that made many people angry. When I first saw your headline, I thought he beat you up, but it wasn't. He just hit you twice with his shoes. This kind of thing often happens among girls, and it's no big deal, but you have remembered it for so long, which requires you to reflect on yourself.

You need to think about why my popularity or personality is not as good as others. Maybe it's because I'm a little narrow-minded sometimes. Or hold a grudge?

It must be hard for you to ask questions. You might as well regard it as a new beginning. From now on, let go of this knot, open your heart and face others with tolerance!

I hope you can get some answers. Have a nice day.
