I took a 13 hour shower...

I have an issue leaving work without taking a shower due to anxiety about asbestos exposure.The showering affects my life greatly due to the time it takes. About half a year ago, it could take an hour to shower, and I would wash 6-8 times. Lately, it has escalated. I've managed to get the wash count down to 4 times, but everything still takes so much time. Now I'm getting stuck at different moments. It takes at least 30 minutes to apply shampoo and shower cream. Rinsing also takes at least 30 minutes, if I don't get stuck rinsing my hair for 1-3 hours before I manage to continue. The latest shower took almost 13 hours, and made my wife coming late to work.

I also need to shower when I come home before I can sit on the sofa, lie in the bed, etc., because I've been in the facility at work after the shower there.

This is destroying my life...

I have tried CBT with ERP without success, and I will start medication once I finish another treatment, as the current medication interferes with this one. I will go to another private therapist who seems more experienced with OCD, and my employer will pay for it.

However, I NEED to shower like a normal human if I want to keep my life as it is, my partner, and my work, as they will get tired of this in the end.
