Quetiapine (Seroquel) for anxiety, anyone have experience with it?

Hello, I'm currently on Vortioxetine for anxiety/depression (having tried several other meds so far... Sertraline, Citalopram, Mirtazapine, Pregabalin etc), but it's not helping with my anxiety at all.

My psychiatrist has now suggested adding a secondary med, Quetiapine or Lamotrigine.

I know these are both anti-psychotics used for bipolar etc, and I was told Quetiapine would potentially be better for anxiety.

Is anyone taking either of these for just depression/anxiety? How has it affected you?

Thanks
