Chako Personality Type, MBTI

Chako personality type is ENTP, which is the ENTP that I have been struggling with for a long time now. I have been reading a lot of blogs and forums about ENTPs and I wonder why I am so different from all those ENTPs who seem to have a lot of fun and seem to be live-wire. I don't have a lot of friends, but I always have a lot of fun with my hobbies and interests. I have been reading a lot about ENTPs and their lives and I feel like I fit into that category, but I feel like something is different. I am constantly upset and angry, and I can't think of anything that I want to do with my life. I feel like all the things that I do are for fun and not for any purpose or goal. I don't know if it's because I won't get anywhere with my goals or life, or if it's because it's just not for me. I'm thinking of getting a job, but it seems like I will get depressed and say "Why should I work?"
