Toxic mould exposure

I have been diagnosed with fibromyalgia for 2 years now but sometimes doubt my diagnosis, I have recently read online an article about someone who thought she had fibro but then later found out after being tested for toxic mould that she had mycotoxins in her system and it wasn't fibromyalgia after all and the symptoms were similar, I am now concerned that this could be the case with me as I was exposed to mould when I lived with my parents about 18 years ago, as I was selling they're house after they passed away I discovered a lot of mould would grow on the dining room walls and I mean a lot, knowing what my Dad was like I realised that he'd just been cleaning it off and painting over it probably for a long time and not only that I used to have mould on my bedroom wall inside my built in wardrobe and my dad would say it was condensation and do nothing about it except paint over it now and then, I have been reading about black mould and am worried I may have been exposed but what I can't find out is would this still affect me now years later or would I be fine as it was years ago, ant advice and help would be much appreciated, I will go to my go but I don't want to sound like a fool as I must drive him mad with my fibro as nothing he prescribes me helps at all
