How do you stay patient as a SAHM 😩😩😩

Ma

I have. 3.5yo, 1.5yo, and 15wo. I’ve been a SAHM since March (I was a teacher but once they closed schools I taught from home and then we had our baby and now I’m taking extended leave). My oldest is driving me absolutely insane. Like to the point I don’t want to be around her. I know she is going through a lot (no more daycare/play dates because of COVID, we moved, and new baby sibling). So I am trying my best. She is acting like a baby all the time, having major potty regressions, is aggressive, and screams/whines constantly. I do my best to stay calm, avoid threats/bribes, and be as positive as I can. But there are moments I just can’t take it anymore! I snap either at her or I have to leave and cry somewhere. Then I feel guilty. I always apologize when I snap, but I still feel guilty. I love her more than anything, but I really don’t like how she’s treating everyone around her and I hate to say it but I don’t like being around her. I don’t know if it’s just the changes but I just feel like a horrible parent all the time 😢 can anyone relate?
