Perhaps you should ask your doctor to try a different medication, sometimes some meds just don't work for you in some way or another.
When I was trying to find something for my anxiety back in the day (in my early 20s) I tried quite a few things that either didn't work like I wanted or made it so much worse. To the extent I gave up on trying to find things for it for years.
Now I just take my ADHD meds (Straterra) and since I've started it (about a year ago) I haven't had any issues with my anxiety (went for a few panic attacks a month to none) so I'm not even trying anything for the anxiety.
