Can CBD oil (CBD: THC 1:1 ratio) give me panic attacks?

I am also working with my Physician on the dilemma. I was using the CBD oil with the ratio of CBD: THC 1:1 for my anxiety, sleep problems, and panic attacks. I started with 6 drops and increased up to 16 to 20 drops, and it all became better. I could taper and reduce my Pari Cr dosage from 25mg twice to 6mg (half a tablet in the morning from 12.5mg tablet) for the past 3 weeks. However, I suddenly started getting anxious and panicky at night once or twice a week. I got the nighttime fear after I started Fluconazole for my anti-fungal infection, and I thought that maybe the tablet was interacting with my CBD oil. So I stopped the Fluco 2 weeks back, but I'm still getting that mild panic and fear before going to sleep. I used the same CBD oil for the past 5 months and did not have any issues until 3 weeks ago. Is it possible to be sensitive to THC over long-term use? Can it be that my CBD oil is giving me the panic feeling? Do I need to change the dosage or change the ratio of CBD to THC?
