I suppose my understanding of and easygoing nature towards other people? Life is hard so you can't expect people to be perfect right?

I had a best friend before. But she turned to be dishonest and started to act like a normie, so our friendship is over. Sometimes I think of her and cry remembering our good times. I've moved to an another country. So I have to adapt into a completely new environment. Now, I only have just one IRL friend, and also we are not that close. Especially at nighttime, I feel a heavy, unbearable burden.
