I can also relate to the being interrupted, and picking my skin. With being interrupted it's really hard not to feel like there's something wrong with you/me/us, or like we're terminally awkward.
jeez, skin picking is difficult to deal with too.... I've been through times when I've worn gloves all the time to get myself to stop, but it's never been long-lasting. don't be too hard on yourself. it's not due to weakness.
