Must the fast be made up if a sticky white discharge is excreted after watching a television series that aroused desire, bearing in mind that the questioner suffers from obsessive-compulsive disorder?

It is obligatory to lower the gaze from foreign men and images if it is with lust, and to be keen on preserving one's fast from sins and obeying Allah. What the questioner described is most likely madhi (pre-seminal fluid). If she is unsure whether it is madhi or mani (seminal fluid), she has the choice to consider it either one of them.
