So I have been a member of 3FC for a couple months now I am have started to notice I am pretty hooked on the site. I have really enjoyed reading the fourms, posting in them, and grabbing advice from the various threads.
I noticed something strange about myself though... I had trouble posting when I felt like I was consistently doing poorly, and on the flip side I felt guilty for not posting. I knew I wanted to post to talk about things and reach out, and I knew the people in the forums I post in are fantastic and would be super encouraging, I just struggled to do so.
So I wanna know how you all feel and how you deal with these types of things.
My question is, how does posting actually make you feel. How do you feel when you don't post? Are there times you could post and chose not to for some reason or another?
Thank you all for your answers I am sure they will help me understand what I am trying to figure out...

do you ever feel yourself changing your diet or exercise because you want to post?
