Why do people neglect me time and again?

Question: Greetings Sir, I belong to a middle class family and I am 34 years old. I have a simple personality. I am very friendly with my friends and family. But my problem is that without a reason, I have always been neglected, overlooked and that too time and again. So in this situation, how do I pacify my mind? This is a matter of great concern for me. Please give me tips on how I can get back my good old days.
