Hi Mate welcome to AFN, you've found the best place to get all the info you need to start growing some rocking autos.
I also myself have been suffering with anxiety over the past few years, and although i have not got a big library of strains i have grown out i have come across a couple that have really helped taking the edge off of things and help me try keep my anxiety on track. From Mephisto both Sour Crack, Deep Blue C have had positive calming effects and have worked well for me, and also Fastbuds Northern Express is a nice calming smoke but will leave you a bit nonfunctional and sleepy compared to the Mephisto strains. White N Bubbly in small doses is also a nice happy good time smoke that takes the edge of a bit, but if over indulged can soon turn very racy and and anxiety inducing rather quick.
CBD oil has also come in very useful for when i have any really bad attacks, so what Medgrower says about high CBD strains make perfect sense but without trying any myself cannot really make any recommendations there, but should give good relief without the risk of getting to racy due to overly high ratios of THC.
The misses also suffers anxiety but does not use Cannabis so this year have grown out some Leonurus Sibiricus to brew up into a tea for her to see if it will be of any benefit at all, have a thread up in the medical section about this plant but have not harvested or properly tested any yet, but will post there when she is off of her meds from her surgery and we get a chance to see how it goes.
