When you're feeling tired try going for a short walk or running an errand (if you can get away). I find a quick walk or running an errand, especially if it's cold out picks me up from feeling tired. Try taking a full day off from devices on a weekend day or maybe both days. Pick up some hobbies with less screen time. When you are on the screen try to limit the time you have so maybe give yourself a half hour to get X complete and work against a timer. If you're doing interesting work usually you're excited to keep going/make progress. I use the pomadoro technique (work 25 min/5 min break) and sometimes if I'm making progress I just keep going through the breaks. Also coding all day and most of the night is probably too much. Typically you only have X hours of productivity per day so if you exceed that you will feel tired sluggish and want to give up. So maybe code in smaller sprints to make the most of your time. There are plenty of evenings I'd like to code more or do a tutorial, but I'm out of cognitive energy and just don't have anything left. I would try coding less, making the most of the time you allow yourself on screen time. Exercise more, take breaks, get out in the cold, try a shower to wake up and see how that goes.
