I signed up just so I could comment on this thread....especially the statement by Zanenna. I am sorry that you spent years of your life and lots of dollars pursuing a profession that you have not found to be what you wanted in life. Wow, from doctor to office manager says a lot about your displeasure with that career.
I have ALWAYS been happy with my selection. It has allowed me to make a handsome salary, more than enough to take care of my family and splurge as well. I have been on hospital staffs, just as respected as other specialists. But I have occasionally seen some people in my class have a similar disillusionment. So what is the difference? I think that a person has to respect what they bring to the table and if they are not confident, appropriately assertive, sociable and willing to "put themselves out there," they will never be successful or happy. If someone in your life is saying podiatry isn't worth a damn, then get a new set of friends.
I have been able to do surgeries that allowed people to return to sports and life in general. I am sent patients by other specialists and FPs so that I can do what I do best. I respect my unique abilities and so I earn their respect. Whatever you choose to do in life, do it well and with joy - podiatry, dentistry, office manager. Life is just too short to do otherwise.
