Need some encouragement ladies

I’m having a SUPER irritable night, and my 5 year old does not use the bathroom by herself, she is very stubborn on her ways with things, and does not play by herself, she won’t have independent play time at all, and usually it’s not a huge deal but tonight I’m so frustrated with her attitude and how I can’t sit down for two seconds (my feet have swelled literally 3 sizes in the ankle and kill me and I’m on them all day) but anyway I’m just finding tonight super hard! Her father helps out as much as he possibly can but she wants me for everything and I literally just started crying because I told her to take her robe off (that’s so soaked from her hair) for bed and she fought me on it like she did everything else today and I just started crying, I feel like a bad mom? Or I’m being irritable about irrational stuff but she’s up an hour and a half past her bed time tonight and let’s just say today was one of those days I needed her in bed at bed time. Tell me I’m not awful for feeling like this & my irritability will subside
