Fingers are crossed!
In terms of "what to buy" there are some lists on online on produce that should be bought organic. Berries are the worst in terms of pesticides and such. Coffee's bad too, tomatoes, apples... Anything with a thicker skin (like an orange or a banana) the skin absorbs most of the chemicals so you're probably safe just eating conventionally grown.
I would also buy any breads and things not just whole wheat or whole grain but
sprouted grain. Food For Life makes a brand of that breads, english muffins and tortillas called Ezekiel. I eat those pretty much religiously (I even use the tortillas to make pizzas!).
It's good to buy organic dairy too. Milk, cheese, yogurt, etc. It's also good to buy organic meat but that's something I never really did. I tried to buy nitrate free turkey though when I could.
As far as exercise goes...getting to the gym is the hardest part even for me still. Is there anything you really like doing? Or anything you've always wanted to try? I started taking spin classes (which I loved for extra cardio), I did muay thai through my school and I took a bootcamp at my gym. Find something you get excited about doing and it may not seem so daunting to try and get going.
I also find going within an hour or two of waking up is the best way to make sure you get it in. I went for a run yesterday afternoon and I was
not feeling it at all. I used to wake up, go to my first class and then hit the gym. It sucks for about a month and then it just becomes routine.
