Is this normal?

I’m 2 weeks postpartum and nursing. My daughter has been wanting to eat I kid you not every 10 mins after she finishes most of the time I don’t even get a single let down bc of how much she’s on my boobs. For the last 4 days. My boobs are really soft and I can’t even squeeze any milk out like I could before her latching so much. I’m so tierd I haven’t gotten like any sleep maybe half an hour here and there in the last 4 days. I don’t know if I just don’t have a supply and should give up with breast feeding but I can’t keep doing this almost no sleep for days on end. It’s not safe when I have to drive my daughter to school and back. Please someone tell me if I should keep going. I don’t want to do formula but Im really really worried.
