Helppp!

My LO is 2 weeks and 5 days and lately he has been super fussy and crying alot. He hasnt let me sleep. I tried everything changing his diaper feeding burping and still nothing! He wasnt like this and all of this is new. The only way he is calm is when he is on my boob but i am so miserable i am planning on stopping and just formula feed. I an currently doing both but dont want to breastfeed anymore. fTM dont know what to do.
