The current conflict with us and iran

Ok so i’ve only ever been diagnosed with severe anxiety.

The whole thing with the us and iran is really bad for my anxiety right now and idk what to do about it. Ive been on my phone constantly checking for updates (like…nonstop) and i can’t sleep. What makes it worse is i’m away from my family. I’m constantly looking at the sky to see if we are under attack. Any sound or movement i feel, i brace myself because i think “this is it”. My husband keeps telling me nothing is gonna happen but i always get the “sense of impending doom” feeling with my anxiety and its 100x worse right now. I just don’t know what to do. I’ve tried distracting myself but it has no effect.

My mind automatically goes to “we’re gonna get nuked”. Is this the reality of it or is there something more realistic?
