I spent over 9 years switching between different SSRIs at different doses. Got the genetic test and found that I can't tolerate them and they cause a worsening of symptoms. That explains why my anxiety had only been getting worse, never better, on them.

Since then, I have tried some medications that the test showed are okay for me, but none of those have worked. Still haven't tried others on the list of approved meds though so can't say if test is worth anything.
