Do you have any underlying health problems that may be causing the skin and hair problems? I see your profile says you are 36. I am 37 and have for a few years now dry, burning skin on my face and at times neck and body. My doctor said it is due to high stress levels and that my liver is not functioning properly (your note of yellow skin could be liver related), which makes sense given the particulars of these years.
(unrelated, but I didn't even know what a Fred Meyer was until I just searched online)
You might give off a different vibe when out and about, which may be misconstrued as suspicious. I doubt it would be for looks, as staff should always be trained well enough to not do things as you noted based on that. I know when my anxiety has been bad I look differently around me to see if people are looking at me, so my guess would be something like this?
If you are able to, get a check up on the health, there could be many reasons but most are treatable.
