cant seem to fast

Good day! I need some help, moral support, advice...or whatever else to get me over this hump with fasting. I seem to be suffering from a terrible food addiction right now. I have fasted in the past with ease...but now I cant seem to get passed day one. Something in my mind triggers me to eat. I have been trying to fast since March...and everytime I start...I cant get over day one, two or three. In the past, I have been able to water fast for about 14 days...now I cant do it. I attribute this to a terrible food addiction which starts lurking in my head around 4pm of the first day. Something in my brain makes me go downstairs and get something to eat...and not even hungry. This issue has caused me to gain about 30 pounds since last year...and I am very upset and depressed about it. Any ideas? I would really appreciate it. thanks
