I have no idea what my anxiety diagnosis is but I think the main reason I was prescribed those medications was the severe state of mind I was in and the fact I refused to try any further AD's because I was worried about increased anxiety and suicidal thoughts. I'm sure a doctor would prescribe these for you since the AD's aren't helping. We really need a little extra care at this time of our lives and sometimes that means taking medication, we can't be strong all the time.
In regards to CBD oil, I've tried various combinations, 25 CBD, 25 THC, 100 CBD(4 THC) and now on 200 CBD(8THC). I found the 100 CBD to be the best for anxiety, gave me about 8-12 hours relief per dose. I ended up increasing to 200 purely because of my pain. THC is better with pain but it doesn't improve your anxiety. The whole medical cannabis is still very under researched and it's very much trial and error with the doses. Also getting the balance right between the CBD and THC is different for everyone. There's also a bunch of other compounds in cannabis that there really isn't a lot of knowledge about. It really saved me when I was at my lowest point and it got me off opiates, so I definitely recommend.
