My stupid brother

So I got my period yesterday, and I had to go to this Christmas race and parade. So my entire family was trying to rush everyone else out the bathroom and when it was finally my turn, I was trying to get some pads, and I put one on trans before I could grab some more they rushed me out the bathroom and I forgot. I had forgotten about my period all morning till I got home and realized so I tried to get in the bathroom and my brother comes in and starts banging on the door and is like “dude I need to get in there” and said hold on. He got angry and was like “for the past year she’s like always in the bathroom.” I have had my period for almost two years, but it’s become a lot more regular and heavier. I bleed through into my first layer of pants, and when I tried to change my pad my brother came back to the door and started listening in. Like wtf?! I get really embarrassed about the whole loud pad opening so I came out the bathroom and said “I can hear you through the walls idiot, stop puppygaurding the bathroom. And I got in trouble with my mom for being rude🤨🙄. I tried to explain that I had an emergency and I was trying to take care of it and she straight up said “you don’t need to be a bitch because someone needs to pee” and I said something back that made her feel bad and she said “well your dad should t be in the back all the time” because she felt bad for blaming it on me so she tried to blame it on somebody else. They’re all dumbasses I swear.
