Thanks.

I don't want to be such a nasty person to others who I know from a logical standpoint that they only want to help me but I've always had this problem to some degree even though I've improved in recent years.

Back when I was a teen/young adult and I was living with relatives, I used to get so angry when they came in my room without knocking and I was deep in thought doing something that I would outright start yelling and cussing for no apparent reasoning all because they dare intruded into the one place where I felt safe and interrupted what I was doing.

When people do stuff like that it feels like that they are barging into my safe zone and I feel threatened when that happens.
