school drop out

I dont know what to do anymore..im depressed this past weeks and i wasnt able to attend any classes..its almost 3 weeks now..my classmates visited me this afternoon and told me that if i dont go to school tomorrow they’ll drop me out..its not like i like that school anyway..i just transferred there this few months ago..i dont feel like going to school tomorrow..i have anxiety and im also worried of what might happen..but honestly..i want to get out of that school too, i want to transfer to some other school so i can start again..but im not sure of what will happen if i got dropout..after i drop out from that school can i just transfer to other school instead?..but im afraid of causing troubles to my parents because they’ll have to pay for my tuition fee again..what exactly does dropout means?..i also wish i can do a online homeschooling instead..
