Question in Current Events

I’m sitting in my dark room where I have spent most of my day. At my computer desk with my scented candle and my lemon, mint water. I have instrumental music playing in the background and I’m trying to process what I have been feeling the last few weeks. If I don’t give myself some time to process how I’m feeling I will go numb and nowhere. So here goes:
Currently I feel that I have outgrown a lot of people in my life and I feel selfish because I want to leave them behind when I start the next chapters I want to write. You see, they are what I call backwards people. Once the going gets tough they go backwards. Back to unhealthy “comfort foods” and back to unhealthy relationships and back to unhealthy thoughts and behaviors and I am now surrounded by people who won’t make positive changes that they want me to help them make. After my friend passed away battling his alcohol addiction I tried to stop saving everybody. I guess I went backwards here and I don’t want to move forward with people who bring me down. I don’t know if I am making sense here but is it selfish of me to completely distance myself from these people who aren’t evolving like me?
