So lost

I served in the Army but saw no combat. I was a father but feel I did not do enough. I innovate and try new ideas but I am not a millionaire. I love but feel so empty. I have so many around me but feel lonely. I feel less than. I am in anguish. I never lived up to expectations. I feel agony each day, a dull pain in my soul. Alone in a crowded room. But I live for others and that is what keeps me alive. Only a MGTOW brother can understand what I say.
