Fussy, Crying, Screaming. Growth Spurt?

I'd be lying if I said the last couple days have been easy. Instead, they have been far from easy. Laila has been really difficult to handle. She's been crying and screaming like never before. And I just don't know how to deal with it. She doesn't anything that she normally wants and she seems to always be hungry. Is this the 6 week growth spurt that I've heard so much about? 

Some days, I don't know what to do. I'm here all alone while Justin works and at times, I find it being too much for me. Some days, I just need a break. Which I feel like I never get. I want to cry some days because I'm lonely and overwhelmed. 

I love L but the past couple days have been so hard on me. It's sad and upsetting and I feel embarrassed. I feel like a bad mom at times for not knowing what to do.

I am really hoping that this is just her 6 week growth spurt and in a few days it will pass. But in the mean time, please pray.
