I agree with what neversickanymore is saying... that anxiety is something that's there to tell you that something in your life needs to change. I used to have THE WORST anxiety ever and thought I would never be able to manage it without benzos or opiates. I was never addicted to benzos, but I did have a prescription for them at one point, and whenever I'd have a bad anxiety attack I'd take one under the false assumption that there was no other way to manage the symptoms. So it's not much of a surprise that my anxiety never went away, I was just masking it. That is until I stopped using benzos, and subsequently opiates (the reason I stopped my benzo script... didn't "need" them anymore once heroin entered the picture), to manage my anxiety and started getting to the root of WHAT was making me anxious.
The answer isn't always apparent, but I can pretty much guarantee you that there is an underlying cause. The nice thing about anxiety is that even though it makes you feel out of control, in reality you actually have way more control over it than you think

That, or you're mistaking another emotion for anxiety. Like for me, I have a hard time distinguishing between anxiety and impatience. I'm better at it now, but before, I'd be waiting for a call or a text or for something to happen... and I'd think I was just feeling anxious... when actually it was just me being impatient, and all I had to do was have a little bit of understanding that I just needed to give things time - not everything can always be about instant gratification.
So my best advice would be to examine each area of your life carefully and pay VERY close attention to anything that makes you feel uncomfortable. Cuz once you can identify that, you can start taking steps to either fix it, make it better, or simply accept it, depending on the situation.
Anyway, this week keeps getting better and better. I have been noticing a huge amount of synchronicity in my life this week, like so much that it's almost ridiculous lol. And it's all happening in an area of my life that I've been putting A LOT of dedication and intention into... so... law of attraction ftw, no joke haha that shit is real!!
