It sounds like your obsession might be having or about to have an impact on your life and marriage. You really need to see a counselor of some kind. Unfortunately, a random doctor or counselor or psychologist might know very little about asbestos. The concern here is that they might not understand how little danger there really is in your situation, or conversely, be unable to convince you of the fact that there is little danger in your situation. And worse, it may be hard to get honest and accurate information by googling for "asbestos", or by looking up "asbestos" in the phone book, since there are entire industries devoted to profiting from asbestos-related lawsuits (some of which are legit, but many of which it has become apparent were bogus to the point of fraud) , scare tactics, asbestos cleanup, etc. You need some independent advice...
So here is one suggestion for you. Go to your regular doctor, or a family doctor that you know and trust. Explain your asbestos concern. If they are honest, decent, and knowledgable, they will listen to you, then tell you you have absolutely nothing to worry about. I imagine this will cost you about $200 or so.
Then find 5 people you know and trust. Preferrably intelligent, honest people. Some higher education (college or beyond) would be best as well (for deciphering and understanding the complex/contradictory information available). Maybe a parent or sibling, a school friend, a co-worker, etc. Explain your situation to them, tell them it is ruining your life and marriage, and ask them very sincerely to please help you. They can do this by looking up information about asbestos on the web, asking questions here, etc., then reporting back to you. If they are competent and honest, they will all tell you that you have absolutely nothing to worry about. This should cost you nothing but some sincere "thank you"s.
And if (when) that does not calm your obsession, you can then go to a phsychiatrist, explain that 5 smart, independent people, plus your doctor, plus a dozen random people on the internet, all tell you that you have nothing to worry about, but that you are still obsessed and it is ruining your marriage. They might be able to help you get over your obsession.
