Nope, they are NOT bad friends NEITHER they are fake.
The truth is they are GOOD friends and they are REAL... But they have their own life to live too. They have their work, they have responsibilities as well. So if they are not there for you in those times that you needed them, stop acting like a brat. The world is not revolving around you. Stop being so selfish and self-centered. They've got their own share of madness to survive through everyday. It is not just you who suffers in this world. Sometimes, it is just your desire of attention that is making you feel like you needed them. You can do it by yourself.
Trust me.
Been there.
Done that.
