So until recently I had someone looking out for me a bit and they would at times ask if something was anxiety. I feel like saying yes at times but like what other things can it be. Could I be describing another thing wrong?

Like yesterday I had similar feelings to when they have asked before but it felt a mix of paranoia and fear. My mind was racing first and then I had a massive headache while still racing thinking of everything, today I've felt a massive low.

Any information or resources would be great.
