I suffer from anxiety and unfailingly feel the need of a warm and long hug from a loved one. This urge to get a hug arises almost twice to thrice a day whenever I’m feeling numb, lost or restless. 
If sometimes gets hard as some of these loved ones (eg: my mother or my partner) don’t find themselves in that accommodating headspace to be able to cater to my needs. Also that their love languages do not include physical affection. 
I understand this rationally but am neither able to get rid of this need nor make my partner/mom empathise with my need of some physical comfort and then warmth. 

Is it usual? Can this neediness be reduced?
