Can anyone help me.

I'm in kind of a similar situation (without the six pack!). I lost 60 lbs two years ago, kept it off for a year and then since August have put 20 back on because of simply eating way too much. I've gotten myself back in control after reading (and following) recommendations in a fantastic book, so that book is my recommendation for you. The book is Dr. Yoni Freedhoff's The Diet Fix. He says many, many smart things including this, "The roles of food, as a pleasure, a comfort, and a social pillar, are part of the very fabric of the human condition, and if it's cheating to be human, well, that's a big problem."

Dr. Freedhoff doesn't think any food should be off limits. He also thinks it's counterproductive to forbid certain foods or severely restrict eating. He writes, "Oftentimes, the folks who rely on forbidding food as a weight management strategy are binge eaters. These are the last folks who should live overly restrictive lifestyles as studies clearly finger overly restrictive lifestyles as one of the primary drivers of binge eating."

Anyway, he has a pretty simple system that works with any style of eating so probably you could do Paleo and make it work better for you. It involves six meals/snacks with adequate calories and protein in each and journalling. He has a 10-day program to get you started. I found the book incredibly reassuring and helpful, and something I can follow for life.

Good luck!
