No energy

I honestly have no energy right now , and I slept in . I have a ton of house work , but I feel so depleted . I feel out I breath and dizzy every time I try to attempt to do anything , not to mention I have a one year old to keep up with . I ended up having to lay him down for his nap earlier then normal because I feel like I'm fixing to collapse. I just want to throw my hands up today , I do not feel like cleaning the house .. It's never ending anyways . I feel like I run around in circles picking up toys and sweeping crumbs . ?
