Health anxiety is taking over my life.

Hey so I’m going to be completely honest here, I have recently referred myself for talking therapy regarding health anxiety as I now have been diagnosed with a chronic pain disorder myself. But when it comes to my children I just want to wrap them in bubble wrap. I have three children, 7,2 and 6 months old. I always think the worse when it comes to bumping heads, bellyaches, illnesses. I hate leaving my children with anyone other than myself, just in case they hurt themselves or get ill… does anyone else feel the same way. It’s literally taking over my life.. I feel so guilty because I even watch my partner with my baby, who I know is completely safe with him but I just can’t help it… does anyone having any coping mechanisms. I also find myself googling symptoms… I keep getting tension headaches to the point where I’m severely nauseous and I keep googling and I sat up for hours last night questioning whether it could be a brain tumour… even though I already know it can be apart of my pain disorder… 😭 I feel like I’m going crazy. I’ve always been very dubious when it comes to H/A but it got worse when my middle son was born I used to count how many breaths per minute he does, and then he cause croup and was hospitalised so now I panic at the sign of a simple cold.
