I think every time I hear a plane go by I think its a nuke thats going to drop in my city
Why would someone think that way?
I saw how America planes nuked Japan.
Consider the odds of what you're afraid of actually happening. You can probably talk about this with someone and work your way through it.
Its best to be prepared for a nightmare.
You are being unreasonable here. The odds of your fears happening is minuscule.
