<human>: Give me the gist of the text in a nutshell

My first term of uni's almost over. I've been trying very hard since week 1 to be on track, gave up 90% of my social commitments, but somehow couldn't bring myself to finish my work over the week so I've gone for tutorials without knowing what was going on. I attend my lectures but I don't necessarily understand them - I record them and play them back; sometimes I take 3 hours to go through a lecture that is 1 hour - would attribute it to an inability to focus. I haven't had the time to make notes (barely have time to finish the reading)...Anyway, everything adds up and now I have a huge pile of work to clear, no notes, and I'm pretty much panicking. I've got about 3 weeks to do something about this - but I'm afraid it may not be enough/ I've got no idea how I can maximise my time
Past threads gave very good study advice, but would be better suited to students just starting school, rather than someone in this situation.

Created a throwaway because frankly I'm really embarrassed about this and I think I may have slight depression - I've been crying nights and having panic attacks in the middle of the day where I can't breathe and have to spend hours calming myself down. It's so stupid to try so hard but end up with nothing at the end of the day...
<bot>: tried hard to study over the semester, ended up immensely underachieving, need tips on how to pull up my socks
