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.
Medication, caffeine in the morning, and some hard cardio in the evenings.
The medication helps overall but impacts my sleep quality, the caffeine makes the mornings easier and also makes me more tired in the afternoons, and the hard cardio makes my sleep quality way better plus makes the following day easier to do things as even though the medication helps it only helps so much.
Basically I hope on my bike (which has been converted to stationary) and drive my heart rate up for about a half hour
Edit: By caffeine in the morning I mean a cup of coffee
