Is my anxiety purely mental, or do my planetary placements play a role too?

Hello, I am Mehul, born in Jaipur on 22 nd September 2004 at 740 AM. I have been reflecting a lot on anxiety. Is it our mind that causes anxiety, or is there something that causes it? It clearly would be the case that, should we not know that the word anxiety was even there, we would not be nervous or worried about small things that do not, in fact, present a danger to our lives? In the view of astrology, would my birth chart indicate whether I am more likely to be affected by some planetary factors that predispose me to this overthinking or restlessness? And are there any solutions or suggestions that might assist me in dealing with it better?
