About my life. What should be done to improve it?

My life hasn't been good. In childhood, my parents expected me to top th class and I did. I got 93+% in 10th and 12th.

After they wanted me to clear JEE, I studied hard and got a rank under 600.

My college life was also not good. I couldn't make close friends. Everyone used to say that college friends will be forever (man I don't have any).

Now as I have got a decent job, my parents want me to marry in 1 year. This time I have confronted them that I will take time to marry. I have to focus on my career first.

Life feels hollow from inside. I want to talk to someone but no one is there.

People used to say "ye kar lo fir life me sab chill hai". I have done almost everything a society can expect but life is not set.
