h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

hi,I have a problem which I dont understand and I wonder if anyone could help shed light on it!?
I am a fairly happy 27yr old mature student working towards my degree goal,but I have something in my life which was only a small compulsion but is now I think beginning to spiral out of control.
When i wake up in the morning I have to make sure i have breakfast and could not leave the house if i hadnt eaten.However i cant just have toast or a bowl of cornflakes it has to be a lasagne or some sort of ready meal.As soon as I feel hungry or if there is food available I will have it and eat until I am really really full-then I feel I will be able to do well in class and not feel unwell or get a headache.All the time throughout the day I think what can I have later to eat-if I ran out of money and could not eat,I really do think my mind would just cave in-and I just couldnt function at all.I am not overweight as yet but feel that this is turning into a bit of a compulsion and I wonder if anyone could help me to overcome this.I used to be a smoker and drinker and have given these both up for over a year now-so I am pretty self-disciplined,but feel I may have replaced it with food!! I never make myself sick or anything as I dont feel guilty for eating loads-I just feel happy and secure when I am full up and know that I^ll be ok if I have lots of food inside me.
Please email me at: [email protected] if u can help me.
