Super mum guilt for snapping at unwell toddler 😕 help

[Sneazymumzy]

I am a mum of 2: 3yo and 9m old. I am solo parenting this weekend and I have a cold. My 3yo was ‘misbehaving’ today and by that I mean not listening to instructions and being more stubborn than usual. I say this because he is a fantastic communicator for his age and we normally negotiate quite well. Anyway, I was losing my patience with him until it turned out he’s ill too and needed a solid nap 😞I wasn’t a nice mum and even mumbled ffs at one point when all he needed was a cuddle. No wonder he asks for his dad all the time. I am just an emotionally unstable witch. My 9m old is sleeping through so I am not like this because of lack of sleep. How do you maintain a more emotionally stable approach with toddlers? I feel awful

example of why i lost it: we drove to an animal park snd he wanted to leave after 20mins and started crying. I got visibly annoyed for having driven him and his baby brother there and paid for nothing but I hadn’t realised he was sick until we got home snd napped himself
