How to stop feeling like I am going to fail all my exams (and everything else in life)?

[nitrogenous]

Every time I have an exam, I always convince myself (and even others) that I will fail, causing so much stress and suicidality only for me to unexpectedly get really good marks. Because of it though, I feel like no one believes me anymore that I might fail my upcoming exams and yet no matter what people say about me and my "intelligence", these feelings never go away. This has also now snowballed into anxiety which causes me to avoid studying and also not be able to focus on my studies, strengthening the argument that I might fail my upcoming exams. I can't keep on living like this and telling myself to end my life if I do fail.. I want to stop feeling this way but I don't know how…

I just failed my finals for the second time, I knew I would fail by the not enough studying I gave in and making it not my principal responsibility, but life just goes on until you figure something out, if you're in a country which your diploma is everything, best of luck and keep it steady, try again with a job on the side if you can, If not, might as well work for some time and do it later if you feel you can do that, and talk without a fuzz with family members
I personally don't know any specific technique for what you're feeling, but you simply have to accept that you're trying to do something and it might go wrong for multiple reasons, if you fail keep it cool, have some buddies by your side helps, that can understand and pass a good time and not get overwhelmed
