Interesting thoughts. it's funny that the one time I am making great progress, I am so terrified of going backwards that I risk hurting myself to continue forward. We will see, if it happens again I'll consider getting help. It's just SO easy to eat whatever you want, then purge and go to sleep happy and wake up looking great. It's always a battle for me, being carb sensitive one cheat meal will have me looking like CRAP for days and I'm not kidding.
Like someone said, get that stuff out of your house.
I take it you are not doing a show, in which case your panic would be more understandable.
Maybe you could alleviate some of the terror of going backwards in realizing that you could get hit by a bus tomorrow and die. Is it really worth all the worry about having a "perfect" physique? It's not.
When it comes down to it, it really does not matter if you screw up and look like crap (to yourself) for days. It's better to be healthy and in control of yourself. You sound very hard on yourself. You cannot let this overtake your life. ....hey I haven't been able to train in a few weeks and I feel like a blob. I know that I can get back to where I want to be...it will be OK. You'll be OK too

Oh and if anyone cares I look GREAT today 
Pics or I'm calling B.S.

actually maybe that's not a good idea!
