Frustrated. Any Advice?

I’m a new parent to 6 week old twins. I’m already back at work (I had no choice) and I’m just feeling consistently angry. Not acting on it of course but I consistently feel angry, depressed and just horrible. Kids cry: I get mad. Dogs bark; I get mad. My partner makes a passive aggressive comment (which doesn’t freaking help): I get mad.

I just don’t know what to do and how to get better. I feel like im just 100% angry and annoyed all the time and it’s a shitty feeling. Im being a shit parent and partner.
