Do some basic orientation: take the PHQ-9 (depression), the GAD-7 (anxiety), and the Maslach Burnout Inventory (https://en.wikipedia.org/wiki/Maslach_Burnout_Inventory)

Then try mindful self-compassion: https://www.compassionintherapy.com/daily-challenge/day1

If you're still concerned you should speak to a professional. Good luck.
