If you look up psychometry it should give you some information to assist you.
Well I definitely don't have the best track record with wanting to give hugs. There are few times when I want to because it feels so overwhelming... Even if I really love someone and want them to know that. Sometimes it's overwhelming because it just feels too emotionally close, but other times it's overwhelming because of the other person's emotions/whatever they're dealing with at the time.
I'm not sure why I fear closeness so much? Does anyone have any ideas about that?
Anyway. Hand shakes are less difficult, but I try to avoid those, too :/ Other people's energies come through every time I'm around them, but with any kind of physical touch it's like I can feel way more.
