Oh bloody hell

MY INLAWS ARE DRIVING ME BATSHIT CRAZY. I HAVE NEVER BEEN SO INSULTED IN MY LIFE. So little background I am 1st generation born in the United states from Mexico on my dads side. I an 2nd generation from the UK on my moms side. I lean more towards my dads side because of where I grew up. Well I have alot of words that I only say in Spanish because of a speech problem I have. And i have a small British accent. ( dont ask how that happened I have no idea)Well i was at my inlaws house and I dropped my plate on the ground and it shattered. And I was already stressed because they are micro managers. And they were trying to tell me that my post partum depression was fake and it was just for attention and bla bla bla ( I tend to ignore them when they act like they know what I am going thrue) well I dropped my plate when they said I should be breast feeding my son. ( I have never produced enough in the first place and it doesn't help with anything I deal with) so I yelled fucking worthless plate in Spanish. Oh lord did i fuck up so badly. They started calling me a worthless spick and every other name in the book. When my husband tried to tell them to stop they turned to him and asked him why he was marrying me? They asked if I was only marrying him for citizenship. That was it I got mad and told them well not that it's any of your business. But I was born in _______ AZ that is about 893 miles from the Mexican border. My dad the one who was born in Mexico came here as a kid with his family legally and my dad the one you have been bad mouthing for the past few mins died of cancer about a year ago. Sooo yah I then cleaned up the plate off the floor and scrolled thrue eve in the car with a sleeping baby in the back seat. While my husband got out things together. * sorry this low key turned in to a something * do you guys think I behaved correctly?
