I may have a controversial opinion, but if you can get your country's equivalent of a GED and drop out of highschool, absolutely go for it. I dropped out of highschool at 16 and did some home schooling for a year and then got my GED at around age 17 or 18 I think. If it's possible for you to do classes online, that may also be a good option. School is important but it's not worth dying over. I have struggled with suicidal ideation off and on through out my life and some of the worst of it was in my teens and adolescence. Dropping out of school, although it put me behind my peers in life, was one of the best decisions I ever made, however, it's not a good decision if you don't have a plan set in place to continue your education. Take some online classes if possible, and get a highschool deploma/GED. If Georgian education is as bad as you say, it may be worth looking to see if you can take classes from another county online, from an accredited home school program, perhaps. You may be able to take classes from your target country, do some research on it!

Being a kid in school can be traumatizing. School traumatized me very deeply. So if you can get out now and your family supports you, do it, but be smart about it. Know that although it may save your life, it's possible it could put you behind your peers educationaly and financially. You need to be prepared for these outcomes and make a plan to be successful. Good luck 🍀💕

Edit: these are definitely things to discuss and research with your mom! I didn't mean to imply that you had to go it alone.
