I do think it possible.

I think perhaps this might be a case of seeking the comforts of having such positive experiences at home. You are away from that and the strings must still be pulling at you.

How were your relationships outside of family while growing up? Did you make friends with your peers easily? Were you - gotta ask - awkward then or perhaps a loner? Did you have opportunity to develop relationships and gain skills?

I have advised people before that perhaps observation is the best tool in such situations. Watch the people around you for how they carry themselves socially - especially their non-verbal comunication. Gaining confidence in your own social interractions I think would result in them becoming healthier, reducing your need to 'latch' on as you have indicated, and becoming more comfortable with the down time between interractions, and strengthen those you have.
