I have been on meds before, Clomipramine first two occasions, Citalopram last time. I have had some CBT previously, while I was taking meds but not experiencing any anxiety but then a few months later I had another bad period with the anxiety because I had book lice in my kitchen.
This time I had already planned this CBT even though I wasn't feeling unwell at the time (stupid NHS can't give it you when you need it, waiting lists etc) and so I had come off the meds in the hope that I could be treated as the real me, giving it my best shot, but then I have become unwell again coinciding with the planned CBT.
I have talked to the CBT Therapist and he doesn't think it a straightforward phobia because I can watch the insects outside or let them run on my hands and for most people I have talked to it is quite "normal" not to want these things to be in your house, most people want to get rid of them, but they take some action to do so and stop worrying about it, whereas I worry myself sick. The last session was focussing on making a plan for how to deal with the ants when I find them, rather than hoping I won't find them, including as much detail in my head of what I will do, so that I am prepared. He thinks it might be the control aspect that is my problem, I want to control my house and keep everything "right" and having these insects spoils that for me so I need to decided what is the "right" thing to do in advance. I have only had three sessions with him so far and now his is on vacation for a couple of weeks.
I think the darkest of thoughts come mainly when I am feeling so depressed by the situation and I just want to escape and not have to keep facing up to each day of life with my problem.
