Health anxiety is the worst.

Couple of days ago, was told my body temperature was 100 degrees. I was outside about 45 mins ago, in the heat. My Body temperature dropped down to 98 about 2 hours later. Well, this has messed with my mind big time. You can’t tell that to someone who suffers from health anxiety. Since then, I literally feel like I’m burning up. I feel my face and I feel warm, I know it’s my mind messing with me. Or might not be. I took my temperature at home underarm and who knows if my thermometer even works well. My temperature fluctuates. I feel my face and it feels warm. But I have been paying attention to it every second of the damn day. Who knows. I breathe and it feels like I’m breathing in a sauna. Suffocating. I’m sure it’s because I’m so concentrated on my breath and also my body temperature. Have been so anxious and stressed over this thinking what could be wrong with me. I already believe, health anxiety has made me believe, I have lymphoma. So this just adds to that fear. My CBC was normal about 3 months ago, so I’m wondering if lymphoma would show up or at least mark as a red flag.

My question-

Can anxiety and stress make your body temperature high like all of the time?

Can a CBC flag lymphoma?

Health anxiety is a B****.
