Take screen breaks, (now more than ever!!) Meet up, Call your friends, call your family if you're on good terms. Spend time with pets. Text your favourite mutual you never speak to if you've got no one irl. Hell, log on a minecraft server if nothing else. Or rewatch your favourite show.
Make sure you eat enough and sleep enough, and take the meds and vitamins that you need. Don't believe anything you think if you're hungry and tired and have been scrolling too long.
Get a therapy appointment if you think you need it.
You can absolutely not take any shortcuts when it comes to your wellbeing right now.
