I'm not sure.. this may sound VERY messed up.
Well, I'm in college, I DO NOT KNOW what I want to be, and this is almost my third year of college. I'm 19 years old and male. I have NEVER had an ambition. Maybe it's borderline disorder based on what I've researched on the net. I have made friends in high school, but none I actually go out with, just hang out with at school, etc. I have NEVER made a friend in college, yet. But, WHY DO I HAVE NO AMBITION to do anything for my future? It's not that I was born as a person without ANY goals, because I have had goals in the past, like lose weight, and I did focus and strive to achieve it, and I did. But, when it comes to education and future career, etc. I am clueless, I don't know where I'm heading. I don't feel like I have a purpose in life. I just want to stay with my parents forever, even though I have thought about moving out and living alone, if I had the money. Please help me find a way to find out what I really want to be in my life, what I want to do, my purpose.. Not just things like, "What are you interested in?" Or, "Do whatever interests you, you have a passion for." I DON'T KNOW what I'm interested in.. I like video games (Role playing games), traveling, camping, I know the world map very well, I have an big interest in hurricanes, etc. But, still, I just don't know what I want to be. I am pressured A LOT by family to get into the medical field ( doctor ), and it's such a burden on my mind. It has caused me to become depressed at times, etc. I know I have NEVER worked hard enough to become a doctor, I don't know. HELP ME PLEASE. Thank you.
