bottle feeding & breast feeding

I was breast feeding & bottle feeding & they told me that it's better for me to breast feed but I don't really have milk & so I started bottle feeding & I got all this stuff told by so many that my bby will be getting sick cuz if bottle feeding since the breast feeding isn't working for me that my bby will always be at the hospital & it makes me mad that ppl be telling me stuff like that any moms that feel like that ? ?
