Dealing with Overwhelming Sensory Sensitivity

This sounds horrible, but I understand because I have trouble being close to people that don't have exceptional hygiene. I can smell everything. If they didn't brush their teeth, if they haven't washed their hair, if they didn't use deodorant, etc. I don't say anything because I'd be embarrassed to be told that I stink, but it's part of why I quit being a hairstylist. On a less bad note, I can tell how bitter the lettuce we use at work will be, or how spicy the jalapenos are just from someone cutting them in the kitchen.

This is definitely an issue for me! Often times I'll walk into the kitchen and immediately smell the earth from a plant more than 10 feet away from me. I've even had to stop feeding our dogs wet food as I can't smell it without dry heaving.
