Well, when I was younger, being in new situations made me feel insecure, and I had to size up. Also with relations to other people I always felt very held back. At some point I just turned that around and still do the sizing up thing, but without the sense of insecurity that used to go with it. I don't fear the unknown any more, instead I've found that I quite enjoy the unknown. And feel secure and safe. Alone or not alone, doesn't matter anymore really. Not in the sense of security.
So ehm, secure emotions, don't think that is the right word... It's more that I don't get emotionally insecure anymore about new things, I can still get emotionally sad, happy, excited or whatever though, it isn't like I just stop from getting emotional.
I just lost the reason to have that feeling of insecurity. Broke through that mental blockade.
