Uh i got that feeling, i also feel like that about "friendship" things
Seem like they only contacted me whenever they have nobody else around or just bored in their free time.
I hate it when i really need to talk to a friend about something important because i feel like my world is crashing down but they act like i don't exist until their problems occur. Among all my close friends, only 1 person is care and be able to notice whenever i get into trouble.
