I lied to my family and now that the truth is close to come up I am considering suicide

So, basically I fed my family with a lot of bullshit about my graduation. Everytime I told myself it was just to keep them fine while I can focus to studying and really finish my studies, but I never followed through. Now they are expecting a graduation I can't deliver. I've told a close family member about some mistake I did that will postpone the graduation, but he just want to fix it by coming with me to university, where I am afraid all my castle of lies will crumble down. I really want to avoid this but I dont think I can. I think it would be better to die rather to let them live the pain of all of this, i think i would prefer to be remembered as a dead weird guy rather than be alive and shunned by the family I love but I betray every single day not putting in the work I should. I suppose it would be a stupid reason to kill myself but i really cant think another way out. I also realize my life could have been so easy but i fucked it all up.
