Anyone else struggle with Health Anxiety

As I write this I am having on of the worst episodes of health anxiety that I have ever had. I’m having bad lower back (deep in the spine) and hip pain with abdominal bloating. After a google search I have seen all of these different types of incurable cancers that cause those symptoms and am now on the verge of a panic attack. I am trying to force myself to stay away from urgent care tonight and wait. I was ordered an abdominal ultrasound for 2 weeks from now by my doctor because she felt that I was extremely bloated and I have a history of ovarian cysts. I have had sciatica flare ups in the past and although this doesn’t feel quite like that, I know rationally, that is is probably something related to that and carrying my kids. However, my mind always goes to the worst case scenario and it’s all I think about. My doctor prescribed ativan and it hasn’t helped. I’m sick of living like this! Has anyone else dealt with this? Have you been able to overcome it?
