The main collocation, I suppose, would be "under pressure" in US, UK, NZ, AUS, Canada etc. That's the common way to say it. But if you want to word it slightly or use a different preposition then other ways work to. You will notice that "she's got a lot of pressure ON her" has that ON! You could not use both under AND on. Choose! So, "she is under pressure" or "she has a lot of pressure on her" or "she has got a lot of pressure on her" (don't forget that ON!) and I'm sure somebody else out there will think of another way of saying it too! (What about "there is a lot of pressure on her" ?)

I'm a Canuk! The use of "facing a lot of pressure" is a well-known usage. She's facing a lot of pressure at work. Is that Canadian English? 🤔

I would say "I have MANY pressures". "A lot of pressure" sounds to me like a stomach problem.

Here are a few examples of the way we might use the word "pressure" in Elementary School (K-5): "I am under pressure to complete the assignment." "Put pressure on the arm to stop the bleeding." "The pressure can increase or decrease due to heat." "They tried to pressure the teacher for more recess." "The bite pressure of large parrots is amazing." "There is so much pressure from above, the principal is exhausted." (Meaning the principal's boss is overworking them) "Deadlines create too much pressure for staff." "At recess, all the pressure was lifted from the student's shoulders and they could forget about their tests for a few beautiful moments." When used to describe the force of gravity on an object, "pressure" acts like a noun or "thing". "the pressure" When used to describe how someone feels, "pressure" acts like a verb. Something that you do. You'll see this with suffixes like "-ed", "-ing", and "-s". "was pressured" "is pressuring" "pressures" Language is fun. Good question. I've never thought about this before.

Yeah it seems like American accent
