Why don't I feel anything like a Leo?

You don't completely seem like you're not a Leo. I went through a time in my life (about 2-3 years) where I was EXACTLY like this. You should reevaluate your life and see what's making you feel like this. I used to depend on my parents for everything too, it's hard; but once you get a job and save money, etc it gets easier being able to depend on yourself. As you get older you'll start to evolve more. Think positive! Being a 'Debbie Downer" is nothing but in your mind, trust me.
