I am sorry to hear that you are going through this. I know from my own experience that depression can be extremely debilitating.

My advice would be sitting your parents down and telling them everything. This may seem daunting, but it is the only way for you to get this off your conscience.

Please don't think about taking your life over this. Education is not more important than your life, and I am sure that your parents would be of the same view.

Please DM me if you need someone to talk to. Or just reply here.
