when it all went bad

So i'm writing this bc of what has been happening in my life for the past one year, so basically last year was my first year in this school which i'm currently in and before this i was in a horrible school for 2 years (not gonna talk about that WORST two years of my academic life) so after i got into this school i was just like usual, quiet one and barely ever talked to anyone. But after a few weeks i started opening up a bit and talking to others which was new to me because i had never done that, i never had any friends or sht, my grades were getting better and better my average from 12/20 became 17-18/20 and i did not fail math like last year (not a single test passed) everything was going alr but suddenly in August i started to maladaptive daydream (which is just spending a lot, A LOT of time daydreaming) and since i had no friends irl i used to just live in my head most of the time and thats when the downfall came, i stopped studying like how i used to do before, mid terms were just a few weeks later in september and everything got bad, my grades fell, and so did my mental health (but i was kinda happy bc of daydreaming cus i didnt realise it before) i only realised this, this year in Feb and hopefully my grades were somewhat saved from 65% to 75%, but still my mental health sucks but im trying my best to save myself and get new friends (forget new friends i have nun so just friends)
