"I'm under pressure" is a catch-all statement. Break it down: Who expects what, and how sure are you of that?
- What did your coach say word for word – and what did you interpret?
- What do your parents really expect, and what do you suspect?
- What expectation is 100% your own?
Very often, after sorting things out, only one real demand remains – and it's usually your own. You can work with that.
