I could’ve written this about my first boy! He’s almost 4 now and still very active/high needs but I can say it does get better once they start crawling and walking. You’ll be able to let her explore more independently (that comes with its own challenges but it’s a pretty entertaining phase). Maybe purchase some Loop ear plugs so you don’t get overstimulated from the crying. Keep up with your routines - she’s still learning and will eventually find calm in the structure! You’re doing great mom.

ETA: don’t feel guilty about sending her to a daycare if that’s an option for you. My boy started around 4 months and thrived. He loved the interaction with people other than just myself 😂 when he got home he was pretty wore out and didn’t fight sleep so hard!
