There are many overlapping symptoms with FM, ME and one or two others I just can't recall.
Sound sensitivity is one.
You really have to leave the room when others are talking.
Try a set of the noise canceling headphones, and play some pleasant music to drown it all out.
You really have to remove yourself and/ or disguise the noise it it may make you very ill.
We have had to install double glazed windows, solid doors with sound proof seals, and carpets to my daughter's room to suppress noise.
Washing can only be done while she is asleep, dishwasher must be off when she is around, no taps running, no electrical equipment, no loud noise, no garden machinery etc.
We have moved to a semi-rural area to escape suburbia with its lawn mowers, whipper snippers, pool pumps and general noise.
