It can be hard to tell them apart. Anxiety and depression often go together. If you have been struggling with anxiety for a while, depression may follow, because it is depressing to be anxious, and so depression often occurs as a consequence of untreated depression.
Anxiety is often described as worrying, fretting, feeling nervous or unsettled, usually for no apparent reason. Of course, it is normal and understandable to feel anxious sometimes, such as before a job interview. When you are anxious, it is hard to relax. It is like having the idle setting of your car turned up higher than it should be – the car is burning fuel but not going anywhere.
When you are depressed, you typically feel like you are weighed down by an invisible weight. You feel as though there is a dark cloud following you around, and you can’t seem to enjoy anything the way you used to, or the way others seem to.
