I need someone to talk too.....?

Ok im really depressed now and need to know what my future could be looking like from the POV of an older person. Im 16 and taking my gcse exams which are "apparently" the most important exams of my life as im leaving school now and going to be seeking further education or employment and there is obviously a recession in the uk. Im only taking 6 exams 2 for english 2 for maths and 2 for relegious studies and English, which is my strongest subject by far i have struggled to complete inside the time limit so i know that A i was relying on is now gone. I have maths tomorow and friday and i am awful at maths so to get a C will be a miracle. Relegious studies a C would also be pleasing. Everything else im doing is a BTEC which are not as significant as Gcse's and i dont think will match up to people leaving my school with 10 + gcse's, everywhere like colleges and 6th forms and apprenticeships require a minimum of 5 gcse's and i dont look set to even have that which is appaling and i am actually very intelligent but just not when it comes to maths, i dont have enough exams to prove im smart due to a reason im not going into, so is leaving with barely any gcse's the end of the world its really worryng me and i dont want to be a failure in life, please help.
