I am a fellow anxiety sufferer myself. I'm trying to ease off my meds to get pregnant and stumbled across this video which is free with amazon prime:
It's for depression (and intestinal problems it says) but I find it incredibly relaxing and I think it's helping with my anxiety as well. I can't do all the poses (I'm a bit new to yoga) but I do the best I can and am getting better every day. I'd say it's worth a shot since you have Prime already. Best of luck!
