depends on the anxiety. if its about whether my tags are good enough, i remind myself that they've been so far and if my partner drops because of one bad tag, oh well. no one's perfect and i don't need the stress that level of perfectionism brings.

if it's a case of putting someone else at a higher priority than they do me, i try to address the slowness with my partner if i can. if i can't, or i do but it doesn't change, i resign myself to a slower pace and branch out to other partners or fill the time with another hobby. or more often, housework.

if it's a bad situation with an rp partner, i remove myself from the situation until it calms down. if it doesn't, or is a cycle, i remove myself from the partner.
