Damp mould and anxiety.

[Stressedafff]

I’m at my wits end

DD just getting over a cold. Bedroom is absolutely covered in mould so I HG’ed the window. I’ve just gone to put her in bed and there’s a smell of it. Not particularly strong

is this safe to sleep in

i have OCD and health anxiety hence the daft question

Should be OK if you've aired the room.
If you rent you need to get on to your landlord.
Try keeping your windows on the latch and locked, don't have furniture right against the wall if at all possible. Have you just turned your hearting on for winter?There's nothing you can do immediately tonight but get on to it tomorrow.
