I used to be a straight-A, highly committed university student. I have been lucky in having been provided with good circumstances in which I could study properly and do well in school. I don't think many people are that fortunate and I have always been trying to make the best of it. But thanks to love, I have turned into the opposite - a highly procrastinating individual who is not committed to the future and lives in her present, thinking about her boyfriend practically every second of her day. I cannot hold multiple thoughts in my head at once, and no matter how hard I try to focus on my readings and work, my mind screens out 90% of the material I read. I am getting anxious and nervous because I haven't even started on my assignment yet. This is very unlike me as I have always been proactive, finishing my work way ahead of time and then revising it later on to accommodate my processing speed and my atrocious short-term memory/big picture processing.
The only things I find myself doing at this point are either daydreaming about my boyfriend or talking about him to my friends. I can't talk or think properly about anything else. When I try to do something else, I always screw up because I am not devoting my total attention to it. And unfortunately, there is no excuse that I could give to my prof - "Sorry, I cannot study well right now because I'm in love, could you please give me some extra marks or postpone my test?" will not work. So then in the eyes of the professor, I would be an irresponsible student who is not trying hard enough. And the more time I spend with him, the more I love him, the more time I want to spend with him, and the less productive I become. Spending time with him and thinking about him gives me an inevitable high, but I have been raised under a doctrine where achievement is everything. Thus, I feel a sense of guilt about my current situation.
I know that this is very much a typical scenario for someone my age, but I haven't been given any feasible solutions up to this point. How should I deal with this?
