I'm glad that you're going to see the doctor on Monday and telling her everything that is going on with you. Is that a psychiatrist that you will be seeing? I hope so, this type of doctor is the best suited to help you with your issues.
In the meantime I would just try to relax and practice some relaxation techniques. I'm sure you know some of them from dealing with your anxiety. It could just be that the medication change is making you feel a little different (which is normal) but these type of medications take some time getting into your system so what you are feeling could just be from anxiety or it could just be that your body needs to adjust to the new dosage and you haven't leveled out to the full effect yet and you just need to give it more time.
Just relax and try to get through the weekend. You'll be talking with your doctor soon enough and she is best qualified to answer all of your concerns.
Take care, Breath and relax...you're doing fine and will get through this. You're probably thinking way too much into it as your friends say they don't see any change in you.
Have a nice weekend and let us know how things go for you on Monday.
