Ok, my title is a bit off.
It's just... I have exams now. I did 2 that went good (I think) but now I have 3 and they're gonna be so hard. Now I'm thinking that I'll fail them all three and I'll have to do them again in august for a retake and I'll fail them again and I'll never have a good future cuz I really want this!
I'm babbling but I'm kinda stressed since I have an exam I'll defo fail in an hour or 2.

So how can I stay calm about this? I already have a degree where I can have a nice job, but it's a bachelors degree and I want a masters degree.
