Being anxious about something is perfectly normal when you consider that it is an emotive state that is designed to keep us alive. From the earliest days of humankind, people have rightly shown caution about things they don't know about or understand fully in case it might do them harm. Of course, as people now understand the world much better than they ever did before, so it can seem as though there is very little to worry about any more. And yet, even though our understanding of the world around has improved, our control over our deep emotional states have not been able to keep track. In other words, we still feel worried about things whether they are the sort of thing we should be rationally concerned about or not.
In this sense, anxiety is something that we all have to accept as one of the many emotions we will feel as we go through life. It is not something that should concern us too much. However, being anxious about things excessively, especially when a cycle of worrying starts to develop, can be a big problem that needs to be overcome. If anxious behaviour is left unchecked, then it can become a habit which leads to negative mental states and could, in the worst cases, also lead to unwanted physical conditions being more likely to develop.
When anxious emotions are a part of a mental health disorder, such as clinical depression or PTSD, they can also feel much more acute than they otherwise would. It is always helpful to try and keep concerns and worries in perspective and realise that we cannot control every situation so that we can lead worry-free lives. Talking about concerns – real or perceived – with trusted friends or even a trained counsellor will often help alleviate the worst of these emotions and break the cycles of negative thoughts that add to them.
