What to do when you are under a lot of stress?

Play Minecraft. Build some stuff.

I already have SU, but I'm always happy to share the word of wisdom: the best stress-relieving solution is to go outside and beat some hobos. It's simple, it's fun and it works. Have fun.

Go exercise. It will help with stress. I usually run to keep my stress down

Listen to some reggae music.

I generally hop on to a game where I can kill hordes of enemies quickly.

playing an instrument

Commit suicide. That always works for me.

Fap!Fap!Fap!

A poo.

go outside and run.
if there's a wooded area, run through there.

there's a small wooded mountain near me, and i run around there when stressed out.

i also love running through the rain..

meditate or listen to some relaxing recordings (and i don't mean the music, which is also great)

Wank like an Olympian.

drugs (medicine drugs i mean)

Don't get in over your head and you'll be fine. Stress is just your body's way of telling you that you're doing it wrong. Don't get in over your head and you'll be fine.

Fellow student here! Exercise! Near my first graduation I was reeeeally stressed so I started thai boxe, it helped a lot, something about trying to not get your Ass kicked help you put everything in perspective :-)

Doing something that can take your mind off of things, like picking up a hobby that you enjoy doing to relax yourself with. As suggested already, music and exercise are great options.

I know what you're feeling at the moment. The best kind of things to do when you're feeling absolutely swamped are the unorthodox ones. This is the stuff I've done and still do when I'm feeling lost.

1. Either take out somebody you know or don't to a tavern/pizza place/coffee shop etc and just have a 1 on 1. The best 1 on 1s are the ones where you sit there for hours only thinking 30 minutes have passed, and you learn a lot more about each other. It's all about asking random questions and slowly trying to get deeper, like how me and my friend went from the taste of pizza to how we both are supporters of Anonymous.
2. Go into a busy place, or a quiet one, with a book, and just sit in the middle and draw. Even if you're terrible like me. The point is not to create a masterpiece. You just need to take notice of the world around you. Just draw whatever comes to mind first, and keep it basic. Hell, write if that's going to be more comfortable. If anybody is giving you weird looks, ignore them and press on. You'll eventually start to feel a lot better about time and how the world works.
3. Build something ridiculous. Disassemble something. Break things. Wether it be completely cleaning out your room, breaking apart and reassembling a computer, or just throwing rocks at boxes, if you're doing something that requires energy or concentration, you'll forget about your problems and push forward. And if you do either of the first two, you'll feel accomplished as well. You don't need to completely make the next sculpture of David, just so long as its within your skill range and its going to keep you occupied for a little while.

There's probably more crazy stuff I do, but those are the ones that have helped me most recently.

Run, throw stuff around and sleep.

Fap, order pizza, eat, sleep.

I'm always stressed 24/7, what I do to ease this situation? Nothing, I'm merging with stress, becoming one with it and losing my mental sanity :) (never had one so it's not a big deal :D )

Go out on a simple walk in nature, in a park, forest, on the beach etc. That is a true stress reliefer.

ASMR :3
it seems to help a lot of people in similar or even worse situations :)

I ussually pick some music and relax for a couple of hours alone when I'm under stress. Just forget all the problems for a while.

Edit: Already have scribblenauts by the way so don't gift it to me :P

I attack my backlog.

Well... when I was under a lot of stress I normally listened to heavy metal, drank copious amounts of Rum, and killed as many people as possible with a knife!!! (In Battlefields Bad Company that is.) I normally woke up the next morning refreshed and ready to go! (with a load of hate mail on PSN)

OH yeah, and I already have the game so please give it to someone else in need! Thank you!
