You said your problem is bit shy
Thats not bad thing I think shy is good but
You have to be courage choose good kind girl and write a paper with your love words you cannot say it and write it in the paper and tell her you a little shy and believe me you will move after that movement you will try and will get what you want just take any movement do anything don't stop and say is shy I will not have a girl... I will not have a job.. I will not have agood life just stop thinking and do anything to be out of that shy

you have two choice
1st choice you should stop what are you doing for 10 days take a short break and think are you right to do that or your father is right that you shouldnot do that work.. Then you will find the answer by your self but 1st take a break to know the right thing when you be away from that work..
2nd choice and that I love it.. You stop now what are you doing and go to your parents and hug them big hug and love them do what they want they will be right but you cannot feel it because you are blind by your work or someone makes you love it that's your problem
