This is why it’s smart for people to put genuine work into maintaining healthy friendships and bettering themselves as an individual.
People default to just getting lazy and selfish refusing to work on healthy friendships, and try to shoulder everything and then collapse when emotional hardship arrives.
Either maintaining or acquiring new. Sometimes it's a lost cause. It's not necessarily that person's fault for being "lazy", it might be the other people being "lazy" to better themselves. Cutting people from your life is healthy, but in this day and age it's just hard to know how to find new people.
With how big the world is now and how accessible news (and "news") is, it's kinda hard to find someone with all the same opinions as you. The key to being a good friend is learning a person's boundaries and tolerances and respecting them.
I distanced myself from my oldest group of friends because I was lucky enough to grow my circle and realize how badly I'd had it for 18 years.
