Hi, I am a Btech ( BE equivalent) Mech engineering student from india. Since high school, I have loved physics as a subject and wanted to pursue a career in theoretical physics. But then due to financial and job security reasons and advice from my parents, I chose Mech engg as my bachelors ( This is by default the go-to field in India). However after spending just the 1st 2 yrs, I found the engg field to be extremely boring, and even got depressed and sick due to discontent. I am currently in my 8th and final semester. I am now desperately hoping to switch to a career in physics, hopefully applying for MS in Physics. However I have heard that a career in physics is extremely challenging, even more so without a BS physics degree. Has anyone else been in my same situation and successfully acquired a satisfactory position? Is switching to a different field at this point completely out of the question? Please help.
