Why does it seem like she is almost spying? Can't wait to leave?

I leave for college on the 20th if august. Praise God! My mom stays in my business. Recent she spyed on me looking out the window at some brothers that live next door.. Like Man I hope she don't blow my phone up with text messages when I get to college, cause when I go that means finally give me my damn space. Like I am really anxious to leave now just because she saw me and stopped just cause I was looking out the window. wtf? But I know it may sound harsh but I ain't going to be crying when its time for me to pack up and be on my way to college, I'll be rejoicing. And like just now she barged in my room!!! wtf?? I only heard one single soft knock, like i didn't say come in. How can i let her know not to blow up my phone with text messages cause she would be the one to do so. Imma start paying y bill tho when I get a good paying job so I wont have to hear they mouth about well I'm the one who's paying half on the bill
