My almost 2 year old REFUSES to eat anything and only wants to breastfeed. Why is this happening?

So my son is turning 2 in April, this has been an ongoing issue since day 1. He has never wanted to eat food, I have been trying for MONTHS, he will starve himself the entire day with nothing in his system & just cry for my boob cause he wants to breastfeed

There hasn’t been one day where he actually ate food, he won’t do it. He won’t even eat baby food, he won’t eat absolutely anything.

I tried even pumping my breast milk into a bottle, he won’t drink it even tho he knows it’s breast milk he won’t do it, he wants it directly from my boob

Today I just haven’t breastfed him at all to get him to eat, it’s 8:33 pm and he STILL hasn’t ate, he refuses to eat still. I don’t know what the hell to do at this point, I have tried everything, even refusing to breastfeed him and he still won’t eat a single thing! What do I do at this point! I’m so stuck, it’s frustrating me extremely bad, this isn’t healthy whatsoever, he’s not a little baby anymore and he won’t eat! That’s just not normal and I’m not even sure what I should even do.
