Months ago, when the whole jab thing started, my mother and father in law were determined to get it, because TV told them so.
I advised them not to, and that they are going to damage themselves, multiple times, I event told them about how I ended paralised for a month as a kid when I received vaccine back then... Nothing... They went and did it. 3 times. So after that I basically told them I don't want to talk about it anymore.
Now my father in law, months later, as expected, got a serious pneumonia, lost ability to walk, or even sit in bed, lost control of his bowel movements, and ability to talk, so we are taking care of him the best we could trying not to loose our minds in the process... Showing up with a smile, trying to make their life easier, paying for bills, paying for medication, paying for diapers, and food, clipping his toe nails, cutting his hair and beard, changing diapers...
So on top of all that, wife and I were "politely asked" last night to respect my brother in law more, since he feels that "a lot is depending on him". Same brother in law who was organising excursions with the rest of the family to go for a group testing, to see what might be wrong with them... The same guy who cannot lift a bed matrace without having 2 people help him, while wife and I are the ones carrying his immobilised father around... Same guys who can buy both wife and me with his salary but is paying way less for their bad decisions, and the first thing he came to us with was "how are we going to divide the expanses"...
So I snapped, and yelled my lungs off. So my brother in laws, hypochondriac ass was insisting on them getting jabbed. They did it and we are stoically dealing with the damage made, because they are our parents. And I am accused that I am not "respecting" him enough by not being knowledgeable in ins and outs of hospitals and doctors and procedures and not getting the ideas "first" about where to drag the patient, next...
I am not proud of myself, my friends. I did not have "I told you so" moment at any point there. But I think that even the neighbors in next building heard about the boundaries that they will never be allowed to fucking cross with me...
The messed up thing is that I feel like a piece of shit, now, for allowing myself to go full dark mode.
I have similar family dynamics and not the same situation, but times I have snapped iver very similar things. You feel like a piece of shot because you're a good person. You're right to say what you said but with some people, they can talk shit all day and you stay in a relationship with them, but you speal up once and they act like you destroyed the family. If this was the outcome, dont be too prideful to cool your jets and even make peace, just dont give in and say you were wrong or anything like that. Being right and making a statement is important in life, but it is messier with family involved and sometimes it is more practical or even necessary to seek peace even when you are wronged.
Sometimes, if you are not planning to cut familial ties, you have to put up with shit and even constant insults. Family is generally worth it but there are lines that can't be crossed and even family can cross lines that cut those ties justifiably.
Don't think you are wrong, just know that you feel like shit because you are the better person and did not prefer it to come to this.
