I want to move on with my life but i dont do anything about it?

Its been three years and I've passed every test on the ged except the math. I went back to retest on the math but failed again. I never study for it. I'm not helping myself I want to move on and someday move out of my parents house but I have no drive . I just don't want to study. And I'm not even workng so I have all day and night to study but I choose not too and just watch tv and sleep all day. I'm not moving and the world around me is always busy freinds and family always on the move but I just remain still. I know I can only help myself but if not happy with my situation why wouldn't I want to change? I deserve a real life I haven't accomplished anything in a very long time. Sometimes I worrie that I'm gonna end up like my uncle 40 something years old still living at home not doing anything I almost start to accept that's who I am. My thoughts on life and laziness is destroying my body physically and mentally. You can tell ithis situation is deppressing me but its AMAZING that I'm doing NOTHING to better myself. Your honest thoughts on my attitude and. I want to be a better person and I want people to be proud of me. If you knowways I can help myself would really help
