I am sorry the full moon makes you anxious. I am also confused about why it being in virgo is bad (that's my sun sign), as from my readings its mostly concerned with earthiness and practicality.
Instead of dreading the full moon, why don't you take it as an opportunity to forgo as many responsibilities as possible, and spoil yourself. Binge watch a TV show you love, draw yourself a bath with some music, take a walk in your neighbourhood and feed the birds, bake or buy your favourite treat, read a chill book (I love reading children/young adult fiction when I'm sad).
The full moon can act as a reminder to take care of yourself and prioritize your wellbeing. Get enough sleep, eat good food, drink water. This is maybe a hard one to keep in mind when you're in the midst of a meltdown, but if you can, keep a glass of water near you at all times. If things start feeling like too much, chug it. It sounds weird but it's worked for me many times.
If you are working and able to take the day off, this might help to reduce the level of stress you experience that day.
Journaling may also be helpful. Write down your anxieties, worries and anything else on your mind and it might help you to work through some of the shadows trying to surface. at the least, it can help to lighten the load a bit.
