1) Make plans: a lot of language schools, embassies and universities offer free entry events. So figure out what you're interested in. If you enjoy film and tv, French language schools often have screenings. If you like cooking, East Asian embassies often do demos. If you like history, universities often offer seminars. Make plans and do them. If you wake up on the day of and don't want to go, that is a sign that you absolutely need to. Go out, try something or learn something, stay for the refreshments and talk to people, and don't put any pressure on yourself to perform in any way, just be in the moment and connect with your interests and people.
2) Eat robust meals: you need to eat. As someone who has been the person who chugs an energy drink down, or has a coffee with an apple, it is not enough. Your mind needs sustenance otherwise you tire quickly and it feels like your brain is leaking out of your ear. But when you eat properly and you have a lot of protein, starch, veg etc in your meals, you feel the difference. So get your favourite cup and plate and put a filling meal on it.
3) Commit to a new hobby. It can be anything. The reason you need to commit is to get into the discipline of needing to get out of bed to do it. Painting, walking, making music etc. Commit to learning or doing something that requires that you get out of bed, and that requires some level of focus.
Bonus: look at your phone usage and if there are apps that you use too much, delete them off of your phone and only use them on desktop/laptop.
