Any other UK / EU investors struggling with double whammy decimation? Holding US Growth stocks in USD, what's your plan?

Title says it all

My plan is to keep holding and investing when I can, but I'm somewhat alarmed.

Since February I've lost slightly less than a third of my portfolio, 10% from USD crashing and 20% from Amazon, Meta, Google, Novo Nordisk and Microsoft crashing

I knew to expect 50% drawdowns, but SPY has just got started and I've already dusted off six figures, concerning.
