Anyone else jump to worst case scenario ALWAYS

I’ve felt sick all day. Nauseous, dizzy, lightheaded, extremely exhausted and just overall unwell. Already convinced myself I have diabetes, cancer, and a heart blockage. Anyone else do this?? I’m trying to be reasonable and tell myself that it’s more than likely just a bug but I convince myself that deep down I “know” it’s something serious. 🤦🏻‍♀️
