You didn't say how long you had been in this job but you're an intern so it can't be really, really difficult
Its been barely a month and i would say i have the easiest job. I think i am just been overwhelmed like you said and need time
For the big things, write them down, and prioritize them. That gets them out of your head at night.
Yeah i do that regularly.
And quit thinking about stress
