I am going through a lot of crazy things. I have mold in my house and I have a lot of problems concentrating.
You should probably consult your local state health dept about the mold. It may need to be investigated in parts of your house that you can't see.
My boss's house had to nearly be gutted because of water running underneath and tons of mold.
Another lady i know it made her extremely ill and now she had a chronic condition from it including memory/neurological and terrible allergies to everything. Not trying to freak you out... just to make sure you kill it all.
Dehumidifier needed? Best wishes with everything.
