school

i was smart I swear but I just can't anymore is it because of my phone? I don't think so but why can't I focus like I used to why do I feel so unmotivated why? why do I try so hard and get zeros? am I not putting enough effort? I won't worry I'll just cheat no one will notice right? one of my teachers have caught me but it doesn't matter I'll still cheat cause if I try again I'll still mess up but when will I stop being so dumb? I hate myself I hate not trying but what do I do? I'm just a stupid teenager anyways...
