I've had anxiety since I was pregnant with my daughter and it's almost always centred around my kids and their health.

Over the past week I've got really anxious over our garage. We've lived here for 9 years and the garage has always leaked (only a little and only in a couple of places). It's almost certainly an asbestos cement roof. It's always bothered me so the kids have never been allowed in there but a long time ago we used to store some of their garden toys in there (the dry side away from the leak). For some reason I've started to panic about it and worry their toys might have been contaminated in the past. I know there's nothing I can do but it's woken me in the night and my heart has been racing. I've managed to make myself feel sick and exhausted. I am already having counselling for my anxieties over the kids' health but this has been on a whole new level this week.

Any help would be really appreciated. Thanks.
