End of the world for me?

I started my undergrad in 2021. After completing my 2nd year, I got a year long co-op offer. I earned around 70k cad during the co-op.

This September, I returned to school after completing the year long co-op. Since coming back, I’ve been struggling to concentrate on my studies because I was out of the academic environment for so long.

And now I feel like I’m probably gonna fail 1 or 2 courses. Probably one but there is a slight chance I might fail 2. It’s gonna be 3.5k for me to retake each course if I fail.

I’m feeling really horrible. Feeling like ending myself for this. Worked so hard to earn the money the whole year. And now because of my own fault if I fail 1 or 2 courses then it’s gonna be 3.5k for each course retake.

I’m feeling so horrible. Don’t feel like living anymore.

How do I convince myself that this is not end of the world? Its hurting me a lot
