Feeling weird

Chelsea
Has anyone every experienced feeling antsy like they just don't feel right?! 
I took an hour nap with my 11 month old still feel exhausted but can't sleep... I feel like I can't get comfortable & restless. Waiting for nurse at Drs office to call back. But I know they're going to think way she's over reacting. 
If you have any advice I would appreciate it.

Thanks in advance ladies.
