Is it just me?

So, all my life I've been a nonchalant person, I don't really care much for anything, except myself. I haven't lived life fully yet, but I portrayed certain emotions that leave people with questions. I mean psychological wise, I question myself daily to know if I'm okay. The problem is I'm too nonchalant, I don't care about anything deeply, I really don't have a passion, dream, or longingsl. All I know is I work hard not for the passion, but because I hate being broke. I feel like I've experienced inner contentment that I don't see the need to put in so much energy in life, I just go by doing whatever I want to do . I really don't know how to empathize with real life bad situations, I've built this notion of a strong person in me that doesn't really feel scared of anything or care about people in general, I relate with people but I don't care enough to know much about their lives, I'm just focused on me. Is it just me??
