its hard to determine what will work best for you physiologically until you try a few strains but definitely do a lil research...i've found that the majority of ppl find relief in Afghan or Skunk dominant hybrids and a few of my favorites for severe anxiety are Skunk#1, SharkShock, Aurora Indica and G13/Sk...but its all a matter of personal chemistry so what works for one person may not work for another, for example i can't handle heavy sativa strains as they make my anxiety worse with racy thoughts, nervousness, etc. but others may have the opposite effect...the rule of thumb is generally indica but you got to experiment a bit...i'd recommend you grow out a few Afghan and Skunk hybrids and see if u find something nice and euphoric...i'd also recommend you clone everything so when you find that 1 in a 1000 you can keep her for good...alll the best in your search
