People who are depressed often have anxiety as well – the two problems
often occur together, and each can make the other worse. If you are
feeling anxious, your mind may be full of busy, repetitive thoughts, which
make it hard to concentrate, relax, or sleep. You may have physical
symptoms, such as headaches, aching muscles, sweating and dizziness.
Anxiety may cause physical exhaustion and general ill health (see Mind's
booklet Understanding anxiety and panic attacks for more information.)
