I love Lavender and use it a lot for my anxiety!
Definitely notice clear effects on my anxiety from it.
I occasionally use benzos as well, so I know how that feels too but the scent of Lavender is very effective on me.
If I'm feeling very anxious I like drinking tea made on Lavender flowers. I also use Lavender oil that I like dripping on my pillow, and a plushie I have for hugging.
Definitely recommend, a lovely flower.
