Worried

Today, i feel pretty sad and guilty. I'm supposed to be submitting my performance task in two subjects, but i chose not to. i have 2 missed tasks in a subject and the other subject, i only have one. I've been doing quite well in school and almost all of my subjects so I'm not really that worried that my grades would drop and i would immediately fail. those two subjects i missed with performance tasks and a written task are minor subjects and i don't really need them as much as my major subjects because I'll be choosing the strand STEM in senior highschool. but, i have quite a high sense of responsibility that's making me feel guilty even if most of my scores are high. I'm pretty sure the missing tasks won't affect my grades much. it might get low but i know I won't fail. although, i do worry that teachers might ask me about my missing task in front of the whole class, and well, since I've been pretty much the person who's known to be focused on studies and responsible in class, I'm a bit afraid about it. 

i chose to not submit it to give myself a break. but I don't really know what to say to my teachers if they ever ask me abt it in front of the whole class. they might ask a specific reason because some teachers need a reasonable explanation, and some of them sees family problems/stress/feeling unwell as an excuse. especially since i had time to prepare and submit it because there are days off school, but yeah. they don't know that at home, my parents asks me to do tasks randomly like chores or such and i also don't really feel comfortable doing school tasks with them being home. 

I feel disappointed with myself to be honest. Even if i try to be kind or nice to myself, i still feel the guilt and disappointment that i cannot do my best of best even if i know that i can do it. I don't know why I can't feel more motivated. I've been less and less motivated lately. I really hate feeling like this:[
