just tell me im worth living for!

life seems to bring do many obsticles, and all i want to know is that im worth your time. you tell me i am, but yet i still have my doubts. you know my stresses and worrys, and i know you tryed to be someone better, but as time goes on it feels like you are sliping away. by that i mean that you arent trying to impress me, the magic is gone to you, and i am standing here worried to death that you might leave me behind. so just know that i am trying for you.
how does that make you feel that a lot of what i do is to impress you?.?.
