Sometimes,I'll rub itemsof food on me, or a non-food item,just to feel the sensory"something touching me",for one.
I'm alone and nobody touches me much
I'll,even,put my elbow in some food(not eatit after that),this is,too,partly because I feel that my hand/lower arm/elbow area gets overused,and dry,too(I think I tend to underproduce moisture in my skin,etc.), I'm afraid of developing Carpal Tunnel Syndrome
,or similar.
