Learn Farsi: حالم بد است، فشارم زیاد است و سرگیجه دارم. - I feel bad, my blood pressure is high, and I am dizzy.

In Farsi, physical and mental states are often expressed impersonally. Instead of saying "I feel bad", you say hâl-am bad ast (literally "my condition is bad"). The enclitic -am (my) shows who is experiencing the state, while the verb ast (is) stays in the third person.

Does "feshâr" just mean "pressure", or specifically "blood pressure"?

The word feshâr means "pressure" in general, but in medical or health contexts, it is the standard way to talk about blood pressure. Adding the enclitic -am makes it feshâr-am (my blood pressure).

Wait, shouldn't "high" be translated as "bâlâ"? Why is "ziâd" used here?

While you can definitely say feshâram bâlâ ast (my blood pressure is high), it is also very natural in Farsi to use ziâd (much or a lot) to describe high blood pressure.

The first two parts use enclitics for a state. Why is "I am dizzy" written as "sargije dâram" without an enclitic?

Not all physical states use the impersonal enclitic structure! For some symptoms, like a headache or dizziness, Farsi uses the standard verb dâshtan (to have). Sargije dâram literally means "I have dizziness". You simply have to memorize which symptoms use ast and which use dâram.
