You can either hire a company to come test your house to see what kind of mold it is, or you can buy a home test kit to possibly see if it will show something.
If it is toxic mold, you will have to move out, as you so my won't heal living in that environment. Sorry to have to say that.
I don't know if clothing can be cleaned well enough, but furniture can't. Maybe you can sell it though to someone who isn't sensitive to mold.
There is a Facebook group you can use, where people post potential living arrangements for those with Lyme or mold issues. https://m.facebook.com/groups/167496480113098?ref=bookmarks
