Based on this, some immediate things that stand out are....the junk and soda cannot be a part of your diet. I understand you've gotten rid of soda which is great, but those carby snacks in between meals are hurting your ability to lose weight. If you don't buy them at the store you won't have them at home to eat, right?
I know it's hard but this is one of the areas you need to try to control. It's OK to snack/graze, but buy healthier snacks like low fat cheeses, protein bars, beef jerky, veggies, fish, chicken, etc.... I see a lot of foods on their that look like they could have toppings/condiments on them like mayo, cheeses, dressings ,etc. Are your sandwiches/salads/quesadillas getting toppings added?
Ideally, you should try to drink more like 96-128oz of water. 64oz is a bare minimum for a normal person.
Also, remember, fat free isn't always the best thing....fat free foods tend to add a lot of sugar to compensate, and sugar free foods tend to add fat to compensate, etc. Be sure to look at the bigger picture. What's more important is calories.
I see a ton of carbohydrates in your diet, and no so much protein. I think if you up the protein and lower the carbs in your diet you will be much better off. If you want, we can go so far as to show you ideally how much protein/carbs/fat you should look to consume in a given day, along with how many calories to consume each day to achieve your weight loss goals.
Ab exercises are going to be fairly ineffective for you at this point in time....at this point the type of exercises you should look to do involve lifting weights and/or getting moving, like walking, elliptical machines, etc.
You should get out and attempt to walk again, that will make a big difference in your weight loss efforts.
This is all great info.
