Firstly, let me reiterate that no matter how hard life is appearing - the world isn't ending. Eventually in many years the world may end but for the moment we have to live in the life we're currently in. You have to always remember that you don't need a new year, new week or even a new day to start fresh.
Whenever you feel stressed or panicked, take a big breath of fresh air then slowly release. Clear your head of all the worry and focus your energy on the one task ahead. I can't say this enough; over the years of schooling I have learnt that doing many things at the once can often end up in a bit of a breakdown. I know for a fact, that I can be quite lazy sometimes when it comes to completing work as soon as I receive it, but when I do, do my work as soon as it is handed to me, I can immediately notice a difference in my mind, body and spirit causing me to feel more stress free and relieved. Try not to let things build up till they overwhelm and keep you awake at night, and if this is your current situation, try taking a step back and look at where your stress is coming from. Consider what you can control - then try your best to work on that.
Spend most of your time focusing on your work, but always remember to make sure to save time for the stuff you love, this might be sitting in the backyard or going to see a film with a group of friends, either way make sure you make time for yourself and not just the workload. Also make sure you ask for help when you need it, don't just sit and guess because you will never learn if you don't ask questions.
Another key to making you stress less is time management and organisation, without either of these things I don't know how I would survive day in, day out. Make sure you find some source of organising like a year planner or a little diary. It can be anything, just make sure you have something to help you organise. It's also very important to stop comparing yourself to the person next to you but instead to the person you want to become. In life you will always have someone who you envy, instead embrace that envy and use it to produce your best work. Embrace your mistakes, don't destroy them with perfectionism, because at the end of the day you will learn from those mistakes and the next day you will strive to fix those mistakes.
