One thing that might help when you actually get to the wake is to have something very simple that you can do without anyone noticing.
If you start to feel overwhelmed, rub the tip of your index finger gently in a circular motion against the tip of your thumb. Concentrate on the sensation of it. At the same time, when you're not having to talk with anyone, you could concentrate on your breathing. You don't need to try to change your breathing, just notice it. It gives you something physical and immediate to anchor your attention to.
Anchoring yourself like this can bring the fear down, and can help stop that horrible escalation where one fearful thought leads to another and another.
You could also keep a little 'touchstone' in your pocket to hold onto if you think you might find that helpful. A touchstone can be, say, a smooth stone, a piece of jewellery, a coin, or anything with a texture you find reassuring.
And you could try imagining a protective cage of golden light around yourself. Not something that shuts you away, just something that gives you a bit of space between you and everything that's going on. You can see what's happening, but you don't have to absorb all of it.
Before Sunday, when you notice yourself already imagining the wake and how awful it might feel, I'd try saying to yourself,
“It's not happening now” and turn your attention to something else whilst lengthening a few of your out-breaths. Because it isn't happening now. You don't have to experience it in advance. You can also use your touchstone, or gently rub the tips of your index finger and thumb against each other.
You don't have to try to make yourself not feel frightened. I think that can actually add another layer of pressure. The anchoring is there to help bring the fear back down when it starts to rise.
And you've already given yourself permission to leave when you've had enough. That's important too.
Can you stand another book recommendation?!
It's called
101 Ways to Find Calm: How to Use Your Body to Soothe Your Mind by Rebekah Ballagh. Below is something from the book. You can do the full exercise while you're out of the house, but you can practise it at home first and remind yourself of it when you're out, if you find it helpful.
