Exposures for health/illness OCD

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.

Hi everyone. I'm feeling kinda scared because I have to wait a whole month to start ERP therapy, but I feel like I need to start doing exposures now because the longer I wait, the more anxiety I get. It just feels like the OCD monster is getting worse. One thing that helps me is asking one person about an obsession I have...asking a person that I trust, and then doing an exposure after I get the "ok" to do it. I feel like I do need 1 reassurance and then I can go ahead and do it. I know i'm not supposed to ask for reassurance at all, but i dont think you're supposed to do ERP on your own right? Does anyone have any suggestions for what to do while waiting for therapy? PS-the reason there is a wait is bc she's on vacation. After she's back we will meet regularly.

So at night I have these intrusive thoughts that I leave the door wide open. This causes me to fear that someone will walk in the house and harm my family. I also have this back massage device. I fear that if I leave it plugged in on accident a fire will happen. So I went down to make sure that it was not plugged in. The thing is that I never used the massager that day. When I went back up I felt like I opened the front door (an entrance to my house) even though I didn't. I had to get my wife to check the door other wise I would not have slept. When I checked it I became more insecure. This has been reoccurence with me.
