I don't know what else I can do

My lo is 2 months. All day, all she does is cry. Month 1 she cried every night 4-9. She would scream. Now she is doing it all day. My days are spent trying to console her. That's all I do. All day. I feel so bad for her. It breaks my heart. I just don't know what else I can do. It's beginning to take a mental toll on me. The dr said she is healthy. And that all I can do is wait it out. I've tried everything. Does anyone have any advice? Experience with this or recommendations?
