Eating right doesn't come naturally to any of us, or we wouldn't be here.
I wouldn't worry about addiction right now. Just focus on each choice you make. Each good choice you make will make the next one easier. I found it helps with things that I crave to set a limit on them. Right now I just want frappes all the time, but if I had them I'd never lose weight. So I stop myself from getting them (every single day as I drive past McD) by promising myself one on my birthday. Then, on the day that you planned ahead of time, go and have your treat, fully enjoying it without guilt because you planned it. Then back on track, setting a new date for your treat.
I hope this is an encouragement, but once you actually start to see weight dropping off, it will give you a boost in motivation, because you will want it to continue. I don't like super restrictive diets, but sometimes they are helpful as a jumping off point. Low carb/ high fat can be really helpful if you just can't seem to regulate.
