Anxiety and depression
When worry starts interfering with daily life
Worry is useful. The question is not whether you worry, but whether worry has started making your decisions for you.

Everybody worries, and worry is not a malfunction. It is a system for anticipating problems, and a person with none of it would be a hazard to themselves. So the useful question is not whether you worry. It is whether worry has started running things.
Three tests
Duration
Ordinary worry attaches to a thing and lets go when the thing resolves. Problem worry outlives its object — it finds a new one. If you resolved the thing you were worried about last month and are now worried about something else with exactly the same intensity, the worry was never about the object.
The clinical marker for generalised anxiety is more days than not for six months or more. Most people have been at it considerably longer before it occurs to them that this might be treatable.
Interference
Is it costing you? Sleep, concentration, patience with people you love, the quality of decisions you make, the number of times you have redrafted an email that was fine the first time.
Control
Can you set it down? Not banish it — nobody does that — but put it aside for an hour and go and do something. If the honest answer is no, that is the one that most reliably distinguishes a worrier from an anxiety problem.
The part people miss: avoidance
Anxiety rarely presents as being visibly frightened. It presents as a life that has quietly narrowed.
You do not take the promotion because of the presentations. You go to the restaurant you know rather than the new one. You stop flying. You do the shopping at ten at night. Each of these is defensible on its own, and none of them feels like a symptom — it feels like knowing what you like.
Here is why it matters: avoidance is what keeps anxiety alive. Every time you avoid something and feel the relief, your brain records that avoiding was what kept you safe. The prediction is never tested, so it is never updated, and the list gets longer.
A useful exercise: write down the things you have stopped doing in the last five years. Not the things you decided against — the things you used to do and now do not, without ever having decided.
What the body is doing
Chest tightness, stomach trouble, jaw and shoulders, a heart rate you notice at three in the morning. Many people arrive at therapy having first been to a cardiologist, which is the correct order — get it checked. Thyroid conditions, arrhythmias, some medications and a heroic caffeine intake all produce a convincing impression of anxiety.
When the tests come back clear, that is information, not a dismissal.
Why “just relax” has never worked
Because the part of the brain generating it does not process arguments. You can know completely that the plane is statistically safer than the drive to the airport and still be unable to board. Reasoning with a threat-detection system is a category error.
What does change it is experience — carefully, at a manageable size, repeatedly. Doing the thing is what updates the system. This is the core of cognitive behavioural treatment for anxiety, which has the strongest evidence base of the available options.
When to get help
The practical answer: when it is costing you something you care about, and you have tried the obvious things and they have not held. You do not need to be incapacitated to qualify. Waiting until you cannot function is a high bar that nobody clinical is asking you to clear.
