Ok, lets look at this.
You are in a situation which is stressful with the regards to the break up.
What will happen is that you will automaticaly, as a survival instinct, look to what makes you feel good.
Just remember, you are lucky it isnt chocolate!
If you can take a step back for a moment, look back at the situation you are in from a seperate standpoint, notice that you are looking for something which gives you that "feel good" then you might find the "need" drops away a little.
I am not suggesting you will lose it but it should reduce. It is a normal reaction in most stressful situations and if you are depressed then this will be polarised.
Some of the other points raised about fetish addiction are a seperate issue - although still very valid and good issues to raise.
Make a list of all the things you have to do in order to move forward and focus on that - it is a pattern inerrupt which will help.
