As another poster said it's not being nasty it's self preservation.
I'm a HSP and have only learned I have this personality type in the past couple of years.
I've never had lots of friends, I'm not interested in small talk and there are only a handful of people in my life I feel comfortable with where I can be myself. And that's totally fine.
I have to watch because I can easily become dragged into other people's problems because when they tell me about them I feel like I want to help. Like I can feel what they are going through.
This is not good for me so therefore I have to improve my ability to withdraw at times.
My focus is my immediate family, DP and DC' s. They are the most important people in my life and everyone else is secondary.
I had an unsupportive upbringing with emotionally unavailable parents and a Sibling who despised me and that was damaging.
I've learned now that it's about prioritising myself and my own family.
Coupled with DP and I both working full time with two young dc's, there is just no time to waste on other people's shit.
I'm just starting to lay down boundaries and I'm in my mid thirties.
Fuck those who drag you down. Toxic waste of spaces.
