You are having dyspeptic symptoms. The abdominal bloating and nausea could be due to H.pylori infection or gastroparesis.
Individuals with anxiety symptoms are prone for ulcer peptic disease ( also caused by H.Pylori). The first step in approaching this issue would be avoiding food items that precipitate these symptoms. Avoid milk and milk products for a week and see whether this makes a difference. You can also take an anti ulcer medication like Prilosec OTC once daily in the night just before sleep.
An upper GI endoscopy with biopsy and a gastric emptying scan may be done to know whether you have any of these.
Please so do check your blood glucose level also as diabetes is one of the common causes of gastroparesis. Consider getting prfessional help for anxiety and related symptoms.
I hope that answers your question.
Please let me know if I can assist you further.
