Should I continue starving?

my graduation is in 20 days

I've been starving for exactly 21 days but i still have 20 more

im eating one cucumber just to stay alive but im getting weird symptoms

my eyes fire all of a sudden and when i wake up i can't open them , heartbeats fast and irregular, hair falling , and teeth and gums in horrible shape , and a lot more

i can't study and it's my final year but i really want to look good

usually when i do this and go back to eating healthy meals i throw up ( not on purpose my body does that) and i end up gaining weight back like i did nothing, all that pain and suffering for nothing

so im just don't know if i should continue or not bc im in pain all day, and i want to pass my exams
