Hello there! There are so many medications out there for those with anxiety. Actually, the best person to ask would be the person you have an appointment to see. It's important that he prescribe meds that are tailored to your needs as we are all different in symptoms, tolerance, physical condition, etc. It may take many different changes in combinations to find the one that works exactly right for you.
Just as an example, I've been on a number of different TCAs, SSRIs & benzodiazepines combos. Gained weight with some
and lost weight with others
It took patience and a number of tries to find the right combo. I hope you & Dr. will find what you need ASAP.
