Fainted while taking blood tests, water fast

Hey today was my 4th day on an only water fast, however i had a doctor appointment set up today and i asked for alot of tests.

The girl taking the tests on me did them very fast and on the last vial everything got so dark and i could not see anything or feel my hands. I told her this and she told me to lay down. I laid on that med bed for atleast 3-5 mins without any improvement. Even though i could not see or feel anything i felt very calm and thought that she took the blood out too fast and messed my electrolytes. I told her to bring me some salt and Sugar but she only found 2 pieces of chocolate. I ate it and felt better shortly after.

Now the problem is, this messed up my fast and started my metabolism again. Im hungry AF atm and to be honest its 10 times worse than the first days. Also feeling very dizzy and confused. Do i stop the fast or push thru and start again..? Thanks
