I'm home from an absence and no one cares
Are you very close to them?
They are just friends, I thought they would miss me more than this.
They may have missed you, but you must understand that they have their lives as well. They cannot check on you all of the time.
I guess, but I'm still feeling the absence.
It is ok to feel like that sometimes. But you need to recognize that sometimes others will not have time for you. That does not mean they do not like you.
