Aw, I'm sorry you missed your appointment, Squiggle!
I completely relate to (and remember) the feelings you're going through now! Don't discount them as ridiculous - they're absolutely 100% valid and reasonable! Moreover it's totally understandable that you resorted back to using unhealthy measures to calm yourself, they've been habitual for so long now, and I'm sure we've all had a little 'relapse' into so-called 'bad' coping mechanisms - it's nothing to be ashamed of at all! As long as you stay safe, that's all we care about, lovely!
Is there anything we can do to help you ride this wave out until your next appointment?
