I am M19. Throwaway because im insecure about this. Pretty much all my consious life i have issues when talking to other peolple and doing everyday stuff. And im not native, sorry if its hard to understand my writing. 

So, did you ever have morning "brain freeze" when your sleepy ass pours a cup of coffe and you suddenly realize you water flows out of your cup straight up on the floor? This happens to me a lot. For example when I want to take off my shirt sometimes i would start taking off pants too and i would realize that i didnt want to take my pants off only after doing so. Or if want grab cookies i would open wrong kitchen cabinet and mindlessly stare at it for 5 seconds.

And there is other issue which i think is connected to the one above. When I talk to people my thoughts would often break off, sometimes i get feeling my thoughts are fast and chaotic so they get lost, my head becomes empty and i will stop suddenly in the middle of conversation. It May be however because of lack of social skills as im introverted and situatoin i think slowly improves.

Also i would sometimes immediately forget what i was asked to do, and i would ask again one or two times. 

I tried to talk about it to my mom, but she said i am stupid and that i want to find problem out of nowhere, so i thought maybe i can get advise here. Is this a thing i should be worried about, am i overthinking it? Or how can i improves situation? And why is it hapenning?
