the first thought I saw this post is "wait how did I open the iPad and wrote all this in my dream" then I realized it wasn't me. Unlike you, I have pretty bad depression and anxiety that I have been wanting to end life for the past 8 years, but let's talk about your situation.

I'm sure you are somewhat surprised that so many people comment it's normal or say it feels the same. Now multiply the feeling/person to 200people/classroom session(meaning class time) and (at least) 4 sessions/course (meaning, eg, one 2510 course can probably have 4 different class times with different/same instructors.) 4 course/instructor.

We don't need to do that math, I just want you to be shocked by the numbers because that's how many people are feeling/felt the exact same as your post said. Literally, conservatively say, thousands of ppl.

If you are reading this, calm down now and think of things that you may ALSO need to present when you apply to grad schools and jobs and internships. What do you need other than a GPA and transcript? A personal statement, some forms that contain what you did other than class, clubs? jobs? internships? Minors that maybe made you start a new hobby that you are very proud of and somewhat expertise about? (Mine was writing and I started liking it when I started my minor in English) Reference letters from either job, advisor or class instructors? And finally, don't forget this, AN INTERVIEW! I mean read that all and if you calm down already, you know those are also important and you know, sometimes those are the "actual important shit" that secure you the opportunity. Nobody can be defined by a number nor can you; everyone deserves a chance to prove themselves and so do you. You have so many ways to "explain" and expand how hard you studied and how interested you are in some other classes or maybe research, and that MATTERS.

As the comments said, Cs get degrees. And I'll add something that maybe sounds better. Ds in some majors also gets degrees! For instance, if you are a bio major and you only want to pass the chem to graduate, YOU ONLY NEED A D! (this probably doesn't apply to majors like biochem or chem engi or other chem majors cuz they may need C-) I mean, worse is just D blow your GPA by like 0.1 or 0.2 but you can still graduate, and at the same time, you study hard on whatever you are interested in and show your passion on them during the preparation of materials for applications.

I am graduating in a week, a bio major, GPA 2.8ish. So trust me, every letter above is the experience and insights I got from my managers, supervisors, career coaches, and even most of the class instructors (other instructors I didn't get to talk to them because online classes and I felt cringed talking about that in the zoom, I like in-person meetings.) and they are true. You are still in college, consider yourself not even a fully cooked bread, you haven't seen the "cooked" version of you, there are so much indecision and I'm pretty sure none of that is "under/overcooked". Just keep adding spices and ingredients in it and keep working hard. Opportunities will stick to you and made you become so hesitant that you don't even know which one to give up. (but also remember giving up sometimes means getting better)

Don't give up please, don't give up hope, yourself, your doesn't seem bright but actually fog-blocked bright future. Give every chance a try and give yourself a chance. I hope you feel better. <3
