Be kind to yourself - Negative self-talk will only help validate the negativity around you.
Say no - Saying no will give you a sense of autonomy over your life that otherwise you'd be lacking by engaging in plans and things you don't enjoy.
Set goals - This will keep your day-to-day motivated so you know why you're working so hard.
Ask for help - If you never ask, how do you grow? If you never ask for things, the answer is always no.
