Everyone deserves hugs and kisses and they can mean so many different things.
Speaking from my own experience a hug or kiss is comforting if I am upset, it is a great way of expressing love and affection and gives a feel of elation. When everything is wrong it can make you feel that things will be ok so if you get the opportunity to hug someone, go for it. Not only will it make you feel good but it will also make the other person happy too so I hope someone will hug you really soon.
