I have a masters degree in electronics engineering. When I was pursuing my B.Tech (Electronics and Communication) I had a nervous breakdown (to be specific BPAD) which was treated. After successful treatment I was able to succeed satisfactorily in my career. I have had to follow strict medications from then and sleep of 8 hours was must and the doctor warned me not to be in tense situations. I qualified the entrance exam for M.Tech with a 97 percentile and I have a severe love towards research now. I have started to fall in love with subjects like signal processing, linear algebra, statistics and probability, machine learning etc, but one professor from a premier institute of engineering and science warned me not to do a PhD, because competition is so heavy nowadays and people like me may have a second nervous breakdown.
I am currently working as an lecturer at a private engineering college. The management people are bothering me which is creating great tensions. I will give you an example: The vice principal was asking for an explanation letter and apology along with lot of scolding for a malpractice done by a student in an exam where I invigilated. They are also compelling us to do a lot of office works and not allowing us to focus teaching itself. What my argument is that since I can tolerate these humiliations and tensions, couldn't I join for a Phd programme and advance my career?
I have tried comparing myself with my teachers in engineering college and to my colleagues (who are certainly healthier than me). One instant I can explain: I had a teacher who when I asked a doubt on optical communication answered me that a teacher hadn't taught that....meaning they were not willing to take a look to the reference text. I am far better than my colleagues here. I regularly clear most doubts in the department.
As a human being who has the right to exist in this world and to support my poor family, and to do justice to myself, let me ask that couldn't I do a PhD in this present world?
Update: I submitted my Ph.D. thesis in January 2020. Of course, there were tough times. But I survived. I got a postdoc position too. :)
