Write down your feelings and thoughts to organise how you’re feeling... then get rid of it! Unload some of your stress by ripping it up and throwing it away.
When things feel overwhelming then break your day down into smaller tasks. Plan the time when you’ll study, when you’ll eat, when you’ll do something fun for yourself, and so on. Remember to also set aside some unspecified time and use it to catch up on tasks that took you longer than expected.
Use mindfulness to distract yourself from the stress you’re facing. One simple way to do this is by immersing yourself fully in a small task. An example of this could be making yourself a warm drink: from the noise of the kettle boiling to the smell wafting from your mug, focus on every little detail of the process.
