definatly. i have some pretty massive social anxiety issues. slipping a tiny into my purse really seems to help. sure i may get odd questions for being in my 20's* and playing with dolls, but i don't care. having something that can stave off a panic attack with me is a greater priority than looking silly. and a tiny is easier to carry than a plushie. lol.
*around here, people in my age group are trying desperatly to throw off "childish" things like toys when they become "grow-ups". glad my social circle isn't that silly but even amongst them i'm still outside the norm with my dolls
