I've lurked these boards since my 30's and posted a few times in 30 somethings, but now I am 40 and not much has changed. Oh I've lost 10 pounds, over 3 years

And I feel just pathetic about it. Sometimes I feel like I'll be stuck this way forever. Being fat is one thing, but I dont feel good either. And I do alot of talking, pitty partying, and not much else. I dont know if I'm tired of it, afraid of it, or am really just lazy. I think I'm all of those things but I dont know why. I have excuses at the ready and boy do I use them. Why do I want this so badly but feel like a self sabotager? Why in the world am I stopping/keeping myself from doing this?? Lately I'm just so down about it. I just feel there is no light at the end of the tunnel. I just want there to be an end to the tunnel, forget the light! I'm not even sure what to say. I have the info, I know what to do, I know what not to do, but how do I light the fire that I know is there? I feel hopeless.
