Hi guys, I am a but new to this sub and I need some advice. I have been feeling so anxious recently and I have never felt this way before.

3 days ago I accidentally stabbed my palm cutting potatoes. The wound was not wide (6mm) but deep (5mm). Initially I didn’t think too much. Rinsed it under water for a few min and stopped the bleeding. Later that night I ran across some articles about tetanus and all of a sudden I got so nervous cuz my kitchen knife was dirty (the potatoes were unpeeled and the skin had visible dirt). 

The next day, I rushed to a nearby clinic and a doctor checked out my wound. She said it didn’t look infected but since it may be dirty she gave me a shot of Tdap (at this point 16 hours have passed since my injury).

I keep telling myself I’ll get tetanus for sure from the dirty potatoes. I had all my tetanus shots as a kid, a booster at 14 (7 yrs ago), and the Tdap I got 3 days ago. But I’m so convinced that nothing will help because the knife was dirty, tetanus is already in my body and soon I’ll end up in the ER.

I know it is very unlikely I get sick but I feel so irrational at this point. How can I convince myself to ease my mind? This has never happened to me before and I feel so nervous 😭
