LOST

I feel so lost right now. I'm too lazy to get things done. I know I should be keeping up with my life but somehow I don't feel like doing anything. I feel so stuffed inside. Like how am I supposed to do this? I wanted to do something but what I don't understand is that I'm not doing anything. I have my plans. I have something to look  forward to but still I can't, I mean I won't do anything about it. It sucks living my life like this. Whining and not doing anything. But I just can't make myself to. I want to but I wont. What's really wrong with me? I know what I should do but still... I'm still here. Never going forward. And I hate that part of me. It really sucks! I feel so empty inside and I don't know why. The things I need to do is clear but why am I this way?..

My friends says I need to grow up and do things my own but I'm too lazy to do so. Can anybody tell me what I should do? Please?
