Unconsciously Done!

Hi I'm already 25 years old but still don't know a lot of things.
I have my own place now, whenever I'm alone I do things that most people at my age know it. For example I just did this now, I boiled milk at a thermos.. I don't know that water is the only thing you can put there. So when the milk boiled it blow like a bomb I was so scared, thinking what may happen if I was there when it pop out.
The milk was scattered all over my kitchen. I spent half day cleaning my kitchen which is I hate.. sometimes i don't eat because i don't what to clean.
I also sometimes plug in switch holding the metal.. because i didn't switch on the lights.
When the outlet is not slightly fixed I use the fork to fix it... because it was slightly inverted.
The electrician didn't fix it... luckily when I did that the wire wasn't attached.. when I asked the electrician to look at it because when i plug something it wont open.
