What happened to my good baby?! 😩

My baby is 8 weeks in two days and up until this past week she has been a pretty good baby, always happy, fine to be on her own for a little while so I can clean my house, and fed every 3 hours through the day and 3.5 to 4.5 hours at night. Now this past week she's been grizzling for a feed within an hour of her last one and she screams unless someone is holding her upright so she can see over their shoulder. At night her feeds space out to about 2-3 hours so I do get a little bit of sleep thank god, but the day time feeds and clinginess are killing me! She won't even sleep in her bassinet so she's in bed with us!! What is this???? A growth spurt? Cluster feeding? I'm worried she's getting into a bad habit but I have no idea how to break it 😩 someone please help 😭😭
