Put your part completed degree on your CV with a caveat like its pending or incomplete. It should get you passed the initial screening. Then it's on you to pass the tech test. Expect to fail many before you get good at them
Don't hate yourself. If you can go a few weeks at a time that's good. Better than me. You are certainly better off for that. Blowing off is not all bad. Maybe feeling shit for a couple of days is a price worth paying for decompressing once a month? I'm not advocating that I would love to stop but at the same time... I also like it and it's part of my culture. Do your best, limit yourself, feel good for your achievements not bad about the failures
Every few years? My experience is more like every 6 weeks in the winter. Even with lock down I have caught the second cold of the season. I am guessing you don't have kids
Without trying to trivialise this - it's a problem I have had and its an easy rut to fall into. Work can be a nice place to hide. However the solution is quite straightforward - stop. Work is not crack, it's actually pretty easy to not do when you try. Just don't do it. 5.30pm and you think about the next thing? Stop. 8pm and you think about opening your laptop? Stop. 6am and you think about getting up and looking at some code? Stop. If you are trying to hide in work it's probably not work that is the issue.
