4. Heart palpitations for small things.

First and foremost: should you find yourself experiencing heart palpitations or any irregular heartbeat, you should schedule an appointment with your doctor to rule out other heart conditions.
Heart palpitations are one of the most common anxiety symptoms, but they can also be brought on by anything as simple as dehydration to something as serious as heart failure. Your doctor will be able to tell the difference and recommend treatment if necessary.
Heart palpitations can feel like your heart is beating abnormally hard or is racing without having done any physical activity to cause a change. Abnormal stress levels and anxiety cause your body to release the hormones that trigger your cardiac muscles to work harder and faster.
If you don’t know what triggers your palpitations, begin keeping a journal of each occurrence so you can narrow it down. Include everything from what you were doing to the amount of caffeine you’ve had that day. A simple change in routine could make a big difference.
5. You feel like you will have a nervous breakdown.

If you feel constantly fatigued, agitated, and tense, it is only a matter of time before you might feel like you just can’t keep up anymore. Some days it may feel like you are one stress away from a nervous breakdown.
In fact, you may have mastered the ability to plaster a smile on your face in public while wondering how long you can hold it together.
Depression and anxiety can also occur at the same time, and for the most part the treatment for one will benefit the other. However, if left untreated, depression and anxiety disorders may amplify your anxiety symptoms and greatly affect your overall health and well-being.
