I have a socket that is open like the protection thingy is gone and everytime i put something in it i see little lightning stuff.
am I able to die if I touch it with some metal or something (i live in germany if this is important)
Almost certainly not. You'll just experience anything from a little to a lot of pain and you'll jerk your hand away from it instinctively. You may also trigger the circuit protection (RCD/GFCI) cutting off the current. I've received multiple shocks from 240V (mains) and never experienced anything more than pain and discomfort. Some of them were very jarring but that's about it.
Electrocution is fairly rare. When it was used as an execution method it often took a long time and required the victim to be restrained and subjected to a continuous current for some time. Most accidental electrocution victims are children or elderly/people with existing heart conditions.
There's lots of information online if you search, giving plenty of details on technical aspects of electric shock in humans. I wouldn't ever recommend it as a means to CTB: it's very painful and unlikely to have a good success rate. The Hollywood myth of chucking a toaster in the bath is nonsense. Even high voltage sources like overhead power lines are more likely to leave you with nasty burns and a long hospital stay.
