Has motherhood drained you as a person?

Baby is about 13 months. Love her to bits. But I feel like a shadow of who I was before all this. I feel constantly tired (gonna get PT soon since the pregnancy has made me pee so much and it still continues to this day) so my sleep is messed up since I get up so much go to the bathroom, I feel like I've lost motivation to do anything but take care of my kiddo. Don't really keep up with hobbies, used to work out but I've let myself go a bit, don't go out much.... I just feel like I'm "just a mom" right now and I hate it. Anyone else?
