I had my daughter when I was 16 years old, since then I have also had a son. So I am 21 with two children. And I feel DRAINED! There are so many days where I know I am still young, but I feel so old! I have all these aches in my body now lol I also have a hard time finding energy and motivation. I used to be so bouncy and lively, but since the kids I just feel blah. I feel so old. Anyone else experience this since having their kids?
