I just cant study, am I just lazy?

The title is self explanatory, I have basically lost all my motivation to be productive and I feel guilty every single day. To add some context, I basically switched schools in my senior year and ever since then I have lost my motivation. I was emotionally dependant on my previous school and friends, I had a lot going on in my life and school was the only thing that kept me going. My new school sucks, they dont teach well, I havent made good friends and I absolutely hate going to school. I skip school most days and I barely attend school. I know this sounds like an excuse to be lazy but I have tried studying and being productive with no motivation but I just cant keep on going, I cant seem to maintain consistency. Even if I manage to be productive and get my work done one day I cant do it again the next day and its only like a week or two later that I can manage to study and stuff. I am extremely worried about my future. My family isnt financially stable enough and knowing that I am basically ruining my life and future this way make me feel terrible, and yet I dont do anything to change that. I feel like all of these are excuses because I still get happy/excited when I am with my friends, I enjoy bed rotting and scrolling on my phone. I am happy whenever I am surrounded by my friends but as soon as I get home I start feeling hopeless again, I stay up most nights crying over it. I feel like I have lost my will to live and often feel like ending it all- But then again I fear I might just be lazy and this might all just be an excuse

Kindly help me out and lmk how I can change this. I have tried setting small goals and everything but I still cant seem to manage to stay consistent for more than a day

I used to be a hardworker and would manage to study for over 12 hours a day but now i cant manage to do that for more than 1-2 hours
