Yeah I understand you on that one. I always feel uncomfortable asking around for anything except weed, but I have gotten some great hookups. I'm now getting medicinal weed and I even had a LSD connect at one point. So, it never hurts to try.
There IS a way to access the Dark Web, you can Google how to access it if you have a computer and the funds for bitcoins (the internet's money, so you aren't getting tracked down ordering with a credit card) so if you're interested, check it out. But be careful. I'm not saying it's 100% safe, I just know it's a legitimate source for drugs.
If you truly act like you have anxiety, it can be easy. But it's really hard to keep up the act, and I don't think it's right to lie to your doctor. Most of them can tell just by your physical outlook if you actually have anxiety. You'll most likely go through a psychological evaluation which is a series of tests to determine your diagnosis. The questions are made to check for anxiety, ADD/ADHD, depression, bipolar disorder, etc.. so you may end up with a diagnosis that wouldn't earn you a benzo. I actually have anxiety, and it was hard enough to get on Xanax at one point without my psychiatrist thinking I was trying to abuse it. I had much better luck with my PCP (regular doc.) 5/6 years on Xanax is a really long time to be on it. Once he/she finally stops taking it, they will go through one hell of a withdrawal. And I can guarantee Xanax wasn't the first thing they were prescribed. If so, that's very odd.
