Too much, too soon

Lyrica has a lot of weight gain side effects. Since you have a variety of medical conditions, it might be wise to visit either a sports medicine doctor or an exercise physiologist (i.e. not just a personal trainer with no educational background) to see what is going on. Also, maybe a registered dietician who works with active people.
You might need to tweak your diet in ways that would be different, because of the medications or your actual medical conditions. One thought that comes to mind is that you don't mention any strength training or core work. Weight loss doesn't come from just cardio alone.
Find a qualified medical professional you can trust; good luck!

@New2ride, do plan on never eating carbs (bread, pasta) for the rest of your life? Whatever changes you made regarding what you eat should be something you can live with long term. Too many folks eliminate things from their diet, perhaps lose weight, then return to their former eating habits and regain the weight. Perhaps learning to eat carbs in moderation vs cutting them out completely. Personally, I can't imagine never eating a slice of bread or having some spaghetti.
