Wind can be a big hassle.
Barry22, I have fought wind for a few decades, sometimes winning
and sometimes losing, and I remember a few of the battles.
I lost one a couple of years ago, after battling weather all the way across New Mexico. When I reached Arizona, near the Four Corners, the wind found another gear, and scared me sincerely.
Understand, I don't lose all these battles. In 1964 I struggled through a storm against crosswinds so severe that I could go faster in third gear than in top (that was fourth). Wearing nothing above my neck, I squinted against the rain and made it home. I would not have bet even money on my survival, yet here I am.
However, we ride top-heavy machines. I recall discussing the issue with a Harley rider at a motel in northern Idaho. I had spent a couple of days leaning right against winds from the north, as I rode I-80 westbound. My load was heavy and high, and my Wee-Strom was new, but I persevered and enjoyed my ride. The Harley rider carried his (much smaller) load low in saddle-bags. On I-90, he faced the same winds that met me farther south, and apparently his tribulations were similar to mine, despite the significant difference in the cross-sections that he and I presented to the winds.
What did I do in Arizona, when the winds scared me? Well, I turned tail and fled for home, and that was the right action. Ahead of me, had I survived Arizona, was the higher and windier plateau of Nevada. Winds in Nevada overturned a semi-trailer. A friend of mine was blown from one lane to another in Nevada, and she was riding a Cadillac.
You have received some good advice, about the brace, and about crouching down, and about carrying loads low down. Probably all that is good, but your best safety equipment is, as always, between your ears. When you feel scared, stop and assess the situation. If you think you should stop for a few minutes or hours, or even days, heed that thought.
There are lots of worthwhile things to do while you wait for better weather.
Good luck on your rides.
