10 week old won't stop crying

My 10 week old daughter won't stop crying. She is an excellent sleeper once she is down for the night. She will sleep from 1 to 10-11 in the morning. So I know I am very lucky. But when she is awake during the day she either wants to be nursing, (sometimes to the point where she is throwing up from over eating), or sHe is crying. I took her to the doctor and she said that she might have reflux or maybe it's colic...... it's exaugsting and I feel so sad for her. I know this stage will pass. But it's just so frustrating. I have gripe water, Ferber colic drops, we've tried the swing, walking, singing, bouncing, leg bicycles ( to get rid of gas), swaddles, pacifiers, leaving her alone to lay down..... everything. I know she's getting enough breast milk because I produce a lot when I pump. Any suggestions?
