I feel like I’m losing my mind. 

I was diagnosed with GAD when I was 12, so I’ve been coping with anxiety for a long time. Right now I’m going through a big change—I’m leaving my job of 3.5 years for a new one. 

First it was the background check. I became panicked that something was going to come up (I’ve never been arrested or anything). I was genuinely convinced, though, that something was going to go wrong with it. Of course I passed it. 
Now it’s the drug test. I haven’t touched any illicit substance in 4 years. I don’t even drink alcohol anymore. I am convinced to the point of panic that im going to fail the drug test (what if my meds come up as a false positive? Why is it taking so long? What if I accidentally diluted my urine by drinking too much water? What if I unknowingly consumed something that could show up as a false positive?). I can see, logically, that this makes no sense. But I CANNOT shake the thoughts. I’ve spent hours reading about false positives. I want to jump out of my skin I have so much anxiety 😞😞 has anyone dealt with intrusive thoughts like this? Somethings got to change, I just cannot live my life like this
