Sorry to hear about your difficulty, you must have read about Section 377 of the Indian Penal Court, which was passed in India a few days ago. Homosexuality is not a disease it is just your preference of sexual partner. Now, it is legal in India too. Your affections are towards a person who seems to be a heterosexual (sexual preference is opposite sex partner), that is why for him it is not normal but for you it is normal. You will have to overcome sexual affection from this person and think about a good friendship and look for another partner.
You should consult a counselor who can support you in these difficult times, but you need not see a doctor, as it is not a disease.
