Hi, first of all it's a normal feeling to be wanting to be in a romantic relationship at this age. It's good that you realise that you have to concentrate on your career and be sound financially. Lot of people do foolish things when they are young and later regret. Getting a partner of your choice is not easy. When the time comes it happens to everyone. Don't think it as abnormal. See if there are any other issues which is bothering you and not making you concentrate in your studies.
Next Steps
Talk to your friends about it. Involve yourself in physical activities like running, trekking, cycling etc.
