It's not about whether you can do it, it's whether you are prepared to consider the sacrifices and the impact it will have on your life.
I considered going to medical school at exactly your age, and with my previous education and experience, I would have had a good chance to do so as part of some of the graduate schemes. I got very excited about it as like you, I wanted it so badly and was kicking myself for not considering it earlier.
That was until I faced reality. I was a single mum of two young kids. I would have had to give up a good income to take up massive loans. I would have had to do placements that could have been anywhere within 50 miles if not more. Commuting would have been impossible, then there was the issue of unsociable hours. Then I started to fear that I was glorifying being a doctor, especially as one of my best friend was a GP and looked as frustrated and miserable as me.
I decided that it really was all a fantasy and moved on, but amazingly, my DD decided to pursue it as a career herself and cross fingers, will be starting medical school in September.
The question is: Can you afford it, do you have the time, brain and energy to dedicate yourself to it?
