Gluten Intolerance

I was gluten free for about a year and feeling great, then I started eating twizzlers and wasn't really thinking about the gluten in them. I was started to feel off all the time. Then I got a really bad cold virus and wanted some warm chicken noodle soup and ate that for about 2 weeks and of course wasn't feeling well because I already had a cold. Then I just completely crashed one day. Started having extreme fatigue and weakness. Muscle pain. Stomach problems. Anxiety and panic attacks. I immediately stopped eating the noodles and went back to gluten free. I noticed that eating oats caused the same reaction. Now it is two months out and I am still feeling weak and fatigued. Other symptoms are hard time sleeping, muscle pain, crying easily, panic attacks, reactions to almost everything I eat now. However it is gradually seeming to subside. Questions...Can gluten have a cumulative affect where the symptoms just keep getting worse the more you keep eating and eventually cause a crash? Can the symptoms last for 2-3 mi the or longer? Can oats cause the same reaction (the oats were gluten free)?
