I feel angry today for no reason!!!

I am so pissed today. Almost the whole day and now it’s evening and it’s worse. I wanna tell everyone to F off. My sister in law sent me her list of things that she got for her baby and I just wanna be like don’t tell me what to do 🤷🏻‍♀️ I feel so angry and caffeinated. But I don’t even drink fizzy drinks, coffee or tea. I feel like throwing a tantrum 😭😭😭
