Am I the Only One?

Disclaimer: I don't regret ever having a kid. My daughter is the best part of my life, and I could care less (well a little) if I'd ever land myself a decent, stable partner in the future. 

But am I the only one who gets tired? Frustrated when I feel like I'm not doing enough? Is it always going to be this way? I know I can't complain. I got myself in this situation (I didn't get pregnant by myself you know), and I've decided to go through with it... but I guess I never thought it would be this difficult, most especially when physically, sometimes I feel like I can't handle it anymore.

My mom would always tell me it really is like this.. when you have a kid, you kindof don't have the right to get tired, or to complain that you're too exhausted.. I know comparing myself to other parents is just plain stupid, and well, just really stupid.. but when I see other parents I know, how come they seem so.. okay? That they have time to go out, and not feel guilty when they go out? Is it because they're partners, and not necessarily single parents? Makes me wonder who takes care of their kid(s) when they do go out.. and sometimes, I couldn't help but think, why can't I have that?

AGAIN, I love my kid, 100000%%%%, and if only I could take her out every time I get the urge to leave, I would. I feel guilty for wanting to be alone sometimes... but when she's borrowed, I can't sleep either. Is this how single parenthood really works?

And now I'm feeling the pressure of earning more.. so I'm exploring other opportunities, and yet still get pressured constantly.. I feel like it's unfair if I asked for a break.. but honestly? I do want one. A guilt-free break where I don't feel guilty about leaving Laela with my mom.. because I have this feeling that every time I get to rest, I get this judgy look from her, because she has to take care of my baby.

It's weird how work has become my "break".. how I get to spend some time by myself, and how 15 minutes of alone time brings me bliss.. I feel guilty, knowing that I feel happy being alone at times..

so am I the only one? Am I so unfair? Does it make me a bad person/mother/daughter to feel this way?
