Do I have anyone that needs me?

I wonder if I’m needed or am I just existing. There’s just this thought that comes into my head when I look at happy families, groups of friends laughing and even a couple just smiling to themselves: do I have anyone who needs me?

They seem so content with life, they are living in the best way they can. Being alone the way I am, even with a family, even with friends who treat me like their blood, even with a partner who tries his best to shower love all that he can, are they doing it because it’s their duty or are they doing it because they want to? I have demons in my head, demons that are chasing me in the day, demons desperate to see me crumble, can you see it?
