I hate that I am being punished with loneliness for not being good at developing and maintaining relationships

Like what material difference is there between me with no meaningful or deep connections in my life and someone who actually deserves to be alone? Why do I have to suffer the indignity of every birthday being a complete non-event that basically nobody comes to because I don't inspire anyone to make any meaningful sacrifice of their time for me?

All I want in life is to make people happy and I'm denied that and treated by the universe like someone who actually wants to make people miserable.
