Tired

Veronica
Hello ladies! I have a question and it may seem weird because we all may be feeling the same way. Lately I have noticed that I have been extremely tired. All I want to do is catch some z's and when I do I awaken to feeling even more tired. My LO is 7 months and I'm nursing her. She wakes up once at 5:30 AM to feed. Then falls back to sleep. 
I'm not sure if this is normal for me to feel constantly tired or I need to boost my green friends and start eating healthy
