Wow when I first started reading books on the HSP trait I felt so seen, heard and understood. It is just so nice to know that there are more people like you. That you are not a crazy person.
To just know that actually you can use the phrase: I am overstimulated and I need space now.
HSP people are more sensitive to the stimulants from the outside world. Over stimulation happens when there are too many impressions from the outside world and there is not enough time to rest and process these stimulants.
The key is to find balance to what is happening around you and your inner world. It is the art of HSP to beware of your boundaries and stay out of the over stimulation zone.
There are many ways and tactics to beware of this.
It is a daily practice to beware of your boundaries and to see this trait as the power it is.
