Why is life so hard

Ok where do I start I was kicked off the cross country team for my bad grades I told my mom she wasn’t mad atleast what I thought day went by fast and my mom came up to me she said so your not init and I was like yeah I can’t do practices or comps anymore and she got mad she made me delete roblox and she took away my phone she’s been on my ass 24/7 I don’t even know how she found out I picked up my phone today so yeah my mom hates me and I’ve been having trouble sleeping everyday it gets harder I wake up more sweaty I feel like shit I’m always tired well my speech and debate teacher ask to talk to me and he says how I don’t do much anymore and that I have an assignment that can effect my grade and I told him that it doesn’t pertain to me so I’m not gonna do it and I feel like he’s been targeting me I was speaking for a debate he pulled me aside and said my thing sounded like ai which made me mad because i actually worked on it and I explained that I didn’t and he said “well I still want to hear your real voice your actually opinions” dude that was I tried and I did good well today I was charging my laptop in class and he moved me so my screen was facing him and he can see from his desk and well that’s when he pulled me aside again and told me that I wasn’t trying I got mad because I couldn’t care less and I was already super tired I got home I was on my phone in the office for a bit and I went to use the restroom and well people started to complain I was taking to long I tried to justify that hey I was in the office for a bit and me and my older sister got into a fight and we said horrible things to eachother and I feel like a bad person I just feel like every thing is going so bad this week and I’m scared that the next few days might be even worse I’m scared and I have to admit I’m scared to even sleep well I can’t even sleep my insomnias horrible my eyes are according to all my friends and I have really big eye bags I have constant headaches and my stomach always feel empty I know most of this doesn’t have to do with insomnia I just wanted to throw those in I just feel like shit
