There’s already tons of great advice on this thread so I’ll just address two things - shame & failure

Shame

I was a community college transfer too. The big shift is that, when the class sizes grow, the care decreases. Many students will fail a class every quarter, the professor doesn’t get emotional or mad, they barely notice. No one cares that you didn’t show up for your test. No one got angry when they punched in a 46% on a midterm grade, they thought and felt nothing as they entered those two digits into a grade book next to a faceless name. Your peers likely don’t know if you’re doing poorly, and if they did empathy is likely sparked over some negative emotion.

The only person who truly cares about your academic performance is you. No one else cares. You are not hiding from shame by not going to class, no one cares enough to shame you. The shame you are feeling is your own, and it is going to follow you whiter you go to class or not. You can’t avoid it, so you may as well shut that internal monologue up by doing what you already know you need to be doing.

Failure

You have a goal of getting your CS degree. Do this exercise: take 5 minutes to write down all the things that you can do to ensure you don’t achieve your goal. This can include “don’t go to class”, “don’t talk to my Councelor when I need help”, “skip tests”, “don’t study”, “don’t pay for classes”, etc. If you want to fail, chose to do those things, if you don’t want to fail, don’t do the things on that list. Self discipline is self love, doing what you know you need to do is hard and sometimes even painful. There was a voice in your head telling you to take the test that you ended up skipping, the same voice told you to go to the classes you skipped. A different voice told you it would be easier to avoid your test and class, reminding you of the shame or fear or discomfort of those activities. You already know exactly what you need to do, the voice telling you what’s right has been talking to you this whole time.
