I found this for you. (Read below!) You will read that the "bloating and gas" can come from anxiety. You will also read at the bottom about "frequent urination" due to anxiety.
When are you seing your counselor? I remember you said that you have a counselor. Hopefully he/she can help you until your appointment with the gastroenologist.
Right now you need to get help for your nerves because once these symptoms are resolved, and another symptom comes up you will fall apart again for days and weeks until you have the results.
Just remember we almost always worry about nothing. Remember how upset you were about "bruguda" you were so afraid you had? It turned out that you have a healthy heart.
And most of all remember if any doctor would think that there is a possiblity of cancer they would call you within two days max.
Believe me I know the feeling of suspense and anxiety about a symptom, but once they tell me its not serious or tell me to come back for a follow up weeks or months down the road I calm down. You have to TRUST the doctors otherwise the "not trusting" and the "what if" will ruin your life.
When they say they don't think its cancer you have to BELIEVE them. They do not gamble with cancer, and big time malpractrice suits.
Good luck!
