Hi there Emily~
All the symptoms you describe are suspicious of you having gluten
allergies. I recommend that you see a gastroenterologist to confirm this . You may also need to get other testing done. However it is advisable to avoid any gluten products since you clearly identify that you are having problems with such products. Gastritis
can also cause the bloating
sensation and you are advised to see a physician who can prescribe medications to counter these symptoms. For all you may be having something that is totally treatable, you just need to find out what your problem is. So, don't worry and see a qualified doctor.
I hope this helps. Take care.
