Feel like passing out, including feeling faint or that you might suddenly blackout is a common symptom of anxiety disorder, including generalized anxiety disorder, social anxiety disorder, panic disorder, and others.
This article explains the relationship between anxiety and the feel like passing out anxiety symptom.
Feel faint, like you are about to pass out, woozy, fall over:
You suddenly feel like you are about to pass out, fall over, or faint. It might also feel as though your legs are weak and that you might collapse. It can also feel like you are unsteady, like you are walking on an unstable surface, or that it’s hard to keep your balance.
While you haven't passed out yet, you think you might. The prospect may frighten you. You may also think, "What if I pass out, what will everyone think of me?" The thought of passing out frightens you, which can cause more symptoms and fear.
This symptom can also be experienced as a dizzy/lightheaded ‘spell,’ that is like having a sudden feeling of being dizzy/lightheaded that then disappears.
This symptom and/or ‘spells’ can come and go suddenly, come and linger, or come and remain for some time. This symptom and/or ‘spells’ might occur rarely, frequently, or persistently.
This symptom can also be characterized as having ‘episodes’ of feeling like you are going to pass out or faint that come and go, or come and eventually ease off, even if only slightly. This symptom can occur in ‘waves’ of stronger feelings of passing out which ease off or completely subside. Sometimes the intensity can increase for an extended period of time, such as days before the intensity decreases again.
Some people experience episodes of this symptom in association with an increase and decrease in their anxiety and stress (this symptom’s intensity and severity increases and decreases with the intensity of their anxiety and stress), whereas others experience persistent feelings of passing out regardless of an increase or decrease in anxiety and stress.
All variations and combinations of the above are common.
The higher the rating, the more likely anxiety could be contributing to or causing your anxiety symptoms, including feeling like you might pass out or faint anxiety symptoms.

What causes a feeling like passing out?
Causes relating to anxiety include:
1. Hyper- and hypoventilation
Taking in too much or too little oxygen. Hyper and hypoventilation can change the CO2 levels in the blood, which can cause a myriad of anxiety-like symptoms, such as feeling like passing out.
2. The stress response
Behaving in an apprehensive manner activates the stress response. The stress response secretes stress hormones into the bloodstream where they bring about specific physiological, psychological, and emotional changes that enhance the body’s ability to deal with a threat - to either fight with or flee from it - which is the reason the stress response is often referred to as the fight or flight response.
Some of the stress response changes cause the body to shunt blood to body parts vital for survival and away from those that aren’t. These changes also cause the heart rate and respiration to increase. And many more. These changes alone can cause a person to feel like they are going to pass out.
When stress responses occur infrequently, the body can recover relatively quickly. When stress responses occur too frequently, however, the body can remain in a state of semi stress response readiness. We call this state “stress-response hyperstimulation” since stress hormones are stimulants.
Hyperstimulation can keep stress response changes active even though a stress response hasn’t been activated. Hyperstimulation can cause the nervous system to act in odd ways, which can affect our breathing and sense of balance.
Behaving in an overly apprehensive manner stresses the body, and a body that’s under sustained stress can become overworked and tired. Feeling like passing out is a common indication of fatigue and/or over tired.

How to get rid of the feel like passing out anxiety symptom?
If feeling like passing out is caused by hyper or hypoventilation, adopting a natural breathing style – relaxed, slower, and a little deeper – will correct the CO2 levels in the bloodstream, which will eliminate a ventilation caused passing out feeling.
If your feeling like passing out sensation is caused by an active stress response, calming yourself down will bring an end to the stress response and its changes. As your body recovers, your body’s functioning will return to normal and a passing out feeling should subside.
If your feel like passing out feeling is caused by persistently elevated stress, reducing your stress and giving your body ample time to recover should eliminate this feeling. Keep in mind, however, that it can take a long time for the body to recover from persistently elevated stress.
If your feel like passing out feeling is caused by fatigue, increasing your rest and giving your body time to build up its energy will eliminate the feel like passing out symptom.
