Well, never forget that you're a hundred times more aware of your hair thinning than anyone else.
Everyone has days they think they look "good" and days they look "bad". In truth, you probably look exactly the same to everyone else. People, to be frank, just don't pay that much attention to how someone looks from day to day.
Did your friend at work today feel they had a "good day" or a "bad day" about how they look? You have no idea! Because you really weren't paying that much attention.
Your hairloss may be bad, it might be not so bad. Whichever, *you* think it's much worse than your friend does, because people are far more worried about how they look than you look.
