Relapses

I have contamination OCD that causes me to excessively wash my hands/clean items with disinfectant wipes. I know I just need to start with small exposures but how do I do that without spiraling? I tried a while back by just touching the outside of my dishwasher and not washing my hands after and it led to me being unable to even exist in my house. I basically lived on my couch for three weeks as it was the only 'safe' space that I had not touched with my dirty hands. I had to take a week off work to clean my house to make it somewhat liveable. I still haven't got round to cleaning everything though so things like my kitchen are still no-go zones that I don't enter. I just don't know how to start ERP without it making everything worse. Any advice would be appreciated. I am not seeing a therapist at the moment due to financial constraints.

So for a while i have been suffering of HOCD combined with a little of ROCD and had massive episodes of anxiety and panic attacks, because of that I lost my attraction and my libido while also being in a relationship and that stresses me bad. Also since the start of the severe anxiety I started to lose it gradually over time and at the moment I do not feel any anxiety anymore while having these thoughts which makes me think that I want this to happen because they don’t disgust me anymore. Any advices on how to hold on and get over my OCD? Also is the disappearing of disgust a sign of recovery or denial?

So maybe the title wasn't the best to to put it but when you guys start having obsessive thoughts how do you stop them before it turns into compulsions and anxiety?
