Not being able to focus can be either or, depression/anxiety. I don't know about passing anxiety, depression can go away, if it's situational.

I have to bring up with my pdoc, this week, my 'jumping a mile', over loud noises. Happened, again, today. Deep down, I know that's something deeper seeded than what I've been in treatment for.

Focusing around chaos, now that's something that takes time and skill and learned coping mechanisms. I live with my three kids, there's always noise going on around me. I work with someone, who I feel, needs to hear noise constantly, most likely part of her upbringing in a larger sized family unit, where myself and other worker, aren't used to so much noise. It can be draining, in that regard.

Anxiety is monitored by a listing of symptoms. Talk therapy can help, but if it's an anxiety disorder, that can be treated by a psychiatrist. If that's the route, you choose, of course.

There are anxiety coping skills out there. If it's that. No one here, in PC, can truly say for sure, dx's are best left to doctors, not fellow patients.
