I want to confess so bad but I feel as if my parents would hate me if I did

Hopefully none of my relatives find this post. I feel as if I'm bipolar, my mood swings are crazy like hell, I get mad at someone & the next minute I'm doomscrolling with no thoughts. I also have severe brain fog, I can't think for shit, I forget paths & tasks. My dad is the type of person to tell you to come fess & that it is okay & the moment you start getting real, he yells at you. My mom is the type of person to do stuff that was specified not to do, kinda like a school snitch. I'm scared, stressed, depressed & simply waiting for my moment of deep talk. I'm starting to run out of things to say, but if you want, you could leave some advice. Thank you, goodbye. Cyall when I post here again
