How do you lower the level of stress, without rubber duckies, stess balls and other material stuff?)

Been there. Attitude. You control it. Try to relax and put it in perspective. Good luck!

Deep breathing, focus your mind on something else or talk to a friend if you can

Chocolate 🍫?
Seriosly now - I've been there yesterday. Some music done it, but I didn't return to work after that 🤕

@tamar well, the worst thing is I've got an allergy from chocolate :p
Music helps, but temporally)

Music, time out, meditation, friends, exercise, chocolate :)

@croccifixiogo i exercise for 4-5 hours a day) it helps for that period, though XD

Concentrating on breathing. This one changed my approach to stress totally:

I don't really buy in to all the hurrdurr, but this guy shows in practice and explains it extremely well.

Exercise releases endorphins which make you feel good. I find it lasts a fair while too and if you do it regularly you can actually become addicted to the feeling and will feel a need to exercise when feeling down or stressed. I don't think exercising with one hand is the same though...
