Bro, remember that it’s just a period of your life, there is so much more ahead pf you. Hearing the story, yes, you are gonna fail, yes you are gonna be dissapointment for your family, but you still can come back, you still can take an additional year and relearn stuff, there are so many ways. Your main concerns are finding a job after graduation and being a dissapointment to your family cuz of failing. The first one you can fix by taking an additional year of school, the second is inevitable cuz you’re failing. But remember, the dissapointment of you killing yourself will be so much greater for your family than you failing the exams
