I feel like my mom is spying me in someway..

Everyday as i come back from school i have the same routine, i come back, drop my things, turn the computer on and rant to my friends about how trashy my day has been, I've been doing this since ever, it helps me to think better. But these days I've been noticing something weird..My mom always knows what happens without me speaking to her. 

These days something made me really upset and when i when to start rant, at the first "I'm so sad" message, suddenly i get called to her room so she can help me. i know she's not checking my phone, as i NEVER let go of it, even when i'm bathing. she may do it when i'm sleeping but i always lock my room from the inside..

I've checked for connected devices, and nothing, dug through her phone, nothing. i'm getting really paranoid and now i feel like ranting but i also feel scared of doing so..i know my friend is real, we do video chats, calls, she sends me videos at school, everything. 

i think i'm becoming paranoid and this is becoming a creepypasta in my r/nosleep profile..
