Worthwhile?

Every step I take, it looks all fake, my smile is blooming, though my act is presuming. The more alive I am, the more smiles I’ll spam, yet I’m afraid, they’ll see what I’ve made. They said, "Your smile is contagious." For i am proud for being couragious the more smiley people get, knowing this was all my doing with no regret. I keep letting people smile, Am i still worthawhile? do they now think im annoying? or they are still enjoying? Im always at people's lowest, but it makes me feel helpless, knwing people wont be there, and things for me.. wont be fair.
