I Have Had Lots Of Trauma And Stress For Past

I have had lots of trauma and stress for past 3 mnths. I run very busy furniture store and have worked past 2 mnths with only 3 days off. My store has no air conditioning and it has been extremely hot, I may not have drunk enough water. Past 3 weeks stomach hasnt felt right and I have felt nauseous. Few days ago I felt lethargic throughout day and vomited that night. The next morning I vomited again watery bright yellow liquid. I feel lethargic, eyes are dark around, I find it a little bit hard to breathe. .I have alpha 1 anti tripsin deficiency. My stomach is now bloated and I feel gassy and my stomach feels like it is moving and performing somersaults and nauseous. my tongue and mouth gets very dry esp. during night time. I feel that certain foods make me feel gassier in the stomach. I'm only burping and passing a small amount of wind. I feel quite tired and have interrupted sleep due to dry mouth and little things like noise or insects can wake or disturb me. Please can you help diagnose. Thank you. Tanya
