Somehow you've managed to hold just about impeccable meter without regular line breaks, and the simple shifting refrain is well placed all the way through.
I'm not actually keen on tick and tickles in the same line -- it seems to easy really. Also, I don't relate tickling to a steady tone at all. It just sounds frivolous.
The concept of seeking solace outside of "safest places" is interesting -- there is comfort in confessing to (near) strangers -- the impersonal places no demands upon us. However, you round it back to acceptance of flaws in the final stanza, and that's where the magic really happens. It's so much more satisfying to climb a mountain than a gutter.
