I am getting tired of this

So, currently I am a first-year engineering student, and I could not make it to any IIT. I got NITs but not with my preferred branches. Now, I am studying in one the best institutes in my state (without any quotas or management quota). However, it had hurt me (for not being eligible to be an IITian) so much that I spent months in depression, excluded myself from the outside world, stopped eating and got frustrated with myself. I wanted to take a drop year, but as my father's retirement is approaching (and being from a middle-class family and all the financial issues), I had to start attending college.

And now, my father is always telling me to work hard for GATE. I understand and respect it, but uttering the same thing again and again wherever I go and whatever I do, is frustrating. He keeps saying, "It's my dream that my son will study in an IIT." It bugs me really badly, makes me feel like it's becoming a burden. Hearing this every day is a torture. It does not matter what I do, whether I am studying or playing or listening to music or travelling, whenever he sees me, he goes on, "Take it seriously. It's my dream that my won will study in an IIT." I am reallyexhausted at this point.

Thanks a lot, everyone! I'll make sure to talk to him. :)
