Why do people think greif equates to weakness or stupidity??

My sister just aggravated me to beyond screaming. My husband has been dead since Aug 21 2023. I was a wreck yes but she just said on the phone ,I can't deal with you tonight your all over the place ,omg cause I told her I don't like people she wants me to talk with and this guy who is scum she should marry him oh not 4 her but good for me ? Wtf and a girl she suggested I talk with leaving me a vm that it's not like me not to answer the phone (I haven't talked to her in yrs she doesn't know me ) so she should call the police for a welfare check omg I'm a grown woman and if I dropped dead my son would notice I don't need her .Thanks just so mad .
