Being there for my husband

For a few years now, my husband has sometimes tics and physical pains.
For example, he may have some trouble breathing, so he continually tries to burp to feel better.
I really want to be there for him and I know how I want to show up: understanding that he doesn’t do it on purpose and that he just tries to feel better, so I’m supporting him as much as I can.
Sometimes, though, it’s so hard!! I feel like he’s not processing emotions (am I neither?!) and the consequences are all of these pains and noises!
It’s hard to keep on showing up, I’m annoyed by the situation!
Could you help me feel more in control?

Thank you so so much!!!
