thanks for your question
first of all I would like to tell you that possible gall bladder
problem is not a big problem to worry as most of the problems in gall bladder are due to gall stones
which are incidental finding in a huge number of humans so you need not to worry. If inflammation occurs in gallbladder
then its called cholecystitis
which can be corrected by antibiotic cover or by surgery.
For anxiety you has been given Alprazolam 0.5 per day, as per my opinion its a correct dose for anxiety and it will relieve you of undue stress of gall bladder problem. But you have mentioned that you are not able to take medicines so one thing you can do is to start with 0.25 mg dose or to take mouth dissolving preparation which are better tolerated than oral preparation.
after night dose of Alprazolam is like a mild hangover, try to take cup of coffee or lime juice and do light exercise, you will see improvement.
For anxiety you can try deep breathing exercises, muscle relaxation techniques
etc. which are very easy to practice. You can take help to you tube
hope I solved your query.
