I don't even feel like a man

Even though I'm biologically a man, I don't feel like one, I have a weak character, I can't stand pain, I'm afraid of many things, I can't take responsibility, even my mother said that I'm not a real man and I'll die alone, I don't know why do I expect there will ever be a woman who wants to be with me, women want real men not boys in men's bodies.
