Loneliness in a new year

I can say that my mood changes a lot. Sometimes I do feel loved and cared for , but in reality I don’t feel like I have any friends or meaningful friendships. Some of the people in my life will tell me to not feel sad because they’re there for me but I don’t feel like they’re being sincere. I feel like I’m always the last option. And that they could care less about me. I came to the conclusion that my friendship is only a kind gesture and of convenience , but in reality I’m not important. I only come across peoples minds when they need something. My feelings of loneliness is not feeling alone but it’s the feeling that no one cares. My mother always told me that I don’t have to set myself on fire to keep others warm. This year I want to disappear ... no one cares right ? Well I don’t care either.
