ok, well I read your whole post and the responses. I may have missed a bit here or there, but I'm definitely assuming you are south asian or some other ethnicity in which parents can be very pushy about kids' (even adult kids' jobs). I am an Indian-American attending physician myself (just completed board certification in my field
🙂).
I think in these cases you need to take some time to separate out your dislike of your parents' over controlling behavior. It's a separate issue as to what you should do in life. I agree with all the posts noting the career path you state that you want (writing, PhD in English) is not really that smart. I'm not trying to be mean. How old are you now? Where do you want to be in 10 years? 20? Do you want to own (have a mortgage on) a home? Do you want to have children (and will you pay to put them through college?) Think about this: do you think your parents LOVE their jobs, or are they more realistic about them and the benefits they confer?
And yes, it is true there are plenty of things you can do in medicine as a physician. Not only are the specialties all different, but you can do different things within each specialty, from subspecialization to working in different environments, to part time work. Yes, many physicians do work part time, and you can make a nice normal salary just doing that (i.e. part time 20 hrs in academics, which is generally lower pay could easily be 50-60k, which a lot of people have to work 40 hrs per week for).
Another word of wisdom, both my parents are physicians. My mother has said to me many times: "no matter what you do, after about 8 years it becomes a little boring". I'm only just getting to the part of my life where I can even half way know what she is talking about, because as I said, I just finished residency last academic year, just completed board certification for my specialty, am in a couple of programs that will be evolving over the next few years, and my husband and I will probably be trying for a first baby in a few years; so I won't be doing enough of the same things to be bored anytime real soon, but I also know I've achieved a lot in my life. I think I would be bored and probably dissapointed if I hadn't pursued medicine.
Several posters have talked about coming to the end of life not having pursued a dream. Again, just have to note, to address cultural issues, if the OP is south asian your viewpoint may not apply (reincarnation/hinduism anyone?)
Well, good luck in whatever you choose. I doubt the whole writing/English PhD thing is the best thing to do, but it's your life.
