Extremely fearful and anxious teen

Hello

i’m 16 y/o - I‘m a UK national but currently in the UAE and I am extremely terrified of the current situation -

we’ve been in lockdown for a week now although things seemed to have eased, so today I went out for the first time since everything started.

although just as we made our way back - we started getting so many emergency alerts/alarms etc and I am really scared

I’m so scared I feel like I’m just paralysed in fear

if anyone has any advice how I can just calm myself down and reduce the anxious panicky feeling it would help a lot, my heart is constantly racing, and any little noise makes me feel like my heart’s jumping out of my body

thank you
