What's going on?

I don't know what's happened to me. Its like September came and I just stopped. I stopped watching what I ate, stopped exercising, stopped caring. Its now November, 2 months later and I'm paying for all the stopping I've done. I haven't weighed myself but I don't need too. I know I'm bigger. I feel it and look it. Mike told me I had a small fat roll in my back. My back was always my pride and joy, no fat rolls ever! Now it too has gone the way of the flab. I'm turning 30 in a few weeks and I don't think that has anything to do with it. I'm perfectly fine with turning 30. I just wish I wasn't almost 170 lbs :p (don't know if I am that weight but feels like it since last weigh-in I was 160something). I'm looking at diet stuff online but I don't really need that. I know what I need to do. Drinking this Dr. Pepper isn't helping me. So how do I motivate myself. How do I make myself get up in the morning and workout and make myself eat healthy? Do I need to go cold-turkey and do a detox? When I've done those before they help me get back to eating healthy. So maybe that will be a start. I don't know though just feeling in the dumps about the weight gain. I'm going to see if I can find my old veggie/fruit detox and do it for 7 days.

Hope your exercise/diets are going well.
