Ate a locally grown organic sweet potato, 1/2 gal of water and a piece of chicken for lunch two hours ago and I'm feeling more tired than I've ever felt while eating paleo. Also the first starch I've had in two weeks, what gives?

Your muscles are probably somewhat insulin resistant (you say you're overweight). I would recommend only eating starchy foods (i.e. potatoes/sweet potatoes) post-workout until you reach a healthier body composition. Post workout your muscles will more insulin sensitive and better able to handle the carbs, and will use them for glycogen replenishment. You have to be consistent with your workouts though for your body to become efficient at depleting and replenishing glycogen stores.
I'd recommend walking briskly (or using a stairmill) every single day for 1 hour in the morning before you eat your first meal. Weight train 3-4x per week. On your days off, if you can stomach it, try yoga or do some "active recovery" (hiking, sports, whatever). Eat your starch post workout. Limit your fruit consumption (not necessary to eliminate it entirely though if you're staying active). The remainder of your meals should be meat and produce, with portioned (you don't literally have to measure) amounts of "healthy fats" which DO help your body burn fat by creating a more suitable hormonal environment. These healthy fats are found in things like mixed nuts, real eggs, avocado, olive oils, and fatty fish (fish oil). As you get closer to your goal body compostion, you can start incorporating more "advanced" strategies like carbohydrate (calorie) cycling and strategic "refeeds"... possibly IF if that puts wind your sails. But that's a little ways down the road. for now, stick to paleo with strategic starch only post (weight training/glycolytic) workout.
do that for 1 year and you'll be looking and feeling like a brand new person. the carbs will not make you tired anymore because they'll just fill your glycogen for later use. they won't be burned immediately for energy only to make you crash shortly after.
I hope that sheds some light. Best of luck to you my friend.

We get somewhat insulin resistant on a low carb diet, because the brain wants to sequester all the glucose for itself. So, when you start eating carbs again, the initial insulin spike is higher than usual, to overcome the insulin resistance. Eventually, insulin wins, and overshoots the mark, which leads to lower blood sugar. Low blood sugar makes you feel lethargic, irritable, and even hungry, depending on how low it goes.
The insulin resistance developed on a low carb diet is transient and harmless, beneficial actually because it is keeping the brain fueled. It should become calibrated to whatever level of carbohydrates you eat, so the lethargy won't keep happening if you decide to keep eating carbs.

If you have issues with insulin, a ton of carbs can spike your blood sugar and lead to a release of ammonia which could make you feel horribly tired. Also, starches and proteins are generally considered a bad food combination, so your lethargy could be related to indigestion.
