I’m disrespectful??

Today I’ve been in my room allllllllllllllll day. Honestly I haven’t been in the best mood today and I’ve just been feeling down due to my thoughts and just life things. I’m 20 years old and I live with my parents. So it’s been a quiet day in the house, they haven’t came out there room either and as I’ve mentioned neither have I. When I find myself in down moods I like to isolate myself because I don’t like projecting my bad mood towards or around others and I don’t like being around my parents majority of the time bc they can be pretty negative themselves and kinda toxic, I love them but it’s true. So my mom came in my room earlier like “hello”? And I responded “Hey” and she started looking at me wanting me to say Goodmorning and I told her it wasn’t morning and she was like “yes it is!” And I had to tell her it was literally 2:50pm....then she proceeded to say “why are you hanging off the bed like this, why are you laying like this?” And she got mad bc that irritated me as she did the same thing last night...I was laying in my room in the dark bc my tv has an automatic timer where it shuts off after being on for a while so after the tv shit off, I didn’t feel like turning it on or turning the light on so I just laid on my phone in the dark in silence, she came in my room like “what are you doing? why are you in here in the dark?” Like why does what I do in the comfort of my room have to be questioned.

Back to today...an hour ago she stormed back in my room saying “it’s now 5:30 and you haven’t came in the room to me or your father, for all you know we could be in there hurt, you’re being disrespectful and this is your last time!” Like how am I being disrespectful?? I just want some alone time to myself especially with the mood I’m in, I even told her I wasn’t trying to be disrespectful and she walked away and closed the door as I was talking. My parents, especially my mom, are the type to try to put everyone else in a bad mood or cause everyone else to have a bad day bc they’re not having a good day...
