The theologian Paul Tillich characterized existential anxiety as "the state in which a being is aware of its possible nonbeing" and he listed three categories for the nonbeing and resulting anxiety: ontic (fate and death), moral (guilt and condemnation), and spiritual (emptiness and meaninglessness). According to Tillich, the last of these three types of existential anxiety, i.e. spiritual anxiety, is predominant in modern times while the others were predominant in earlier periods. Tillich argues that this anxiety can be accepted as part of the human condition or it can be resisted but with negative consequences. In its pathological form, spiritual anxiety may tend to "drive the person toward the creation of certitude in systems of meaning which are supported by tradition and authority" even though such "undoubted certitude is not built on the rock of reality".
Experiencing a chronic medical condition or severe or frequent illness can also increase risk for anxiety disorders, as well as dealing with significant illness of a family member or loved one. Given that several medical conditions have been linked to significant anxiety, in some cases a physician may perform medical tests to rule out an underlying medical condition. For instance, thyroid disease is often characterized by experiencing significant symptoms of anxiety. Menopause, heart disease, and diabetes have also been linked to anxiety symptoms. Additionally, drug abuse or withdrawal for many substances is characterized by acute anxiety, and chronic substance abuse can increase risk for developing an anxiety disorder. Anxiety can also be a side effect of certain medications. Experiencing significant sleep disturbances, such as difficulty falling asleep or staying asleep, may also be a risk factor for developing an anxiety disorder.
I’m not sure if this counts as a panic attack, but lately I’ve experienced instances where my head feels like it’s being squeezed, I feel really dizzy, and I get an intense fear of becoming schizophrenic because In that moment it feels like I’m going crazy. It’s happening right now and I’m kind of freaking out because the feeling won’t stop. I’m worried that it’ll never go away and I’ll be like this forever. Hopefully this is just a panic attack?
Anxiety can be experienced with long, drawn out daily symptoms that reduce quality of life, known as chronic (or generalized) anxiety, or it can be experienced in short spurts with sporadic, stressful panic attacks, known as acute anxiety. Symptoms of anxiety can range in number, intensity, and frequency, depending on the person. While almost everyone has experienced anxiety at some point in their lives, most do not develop long-term problems with anxiety.
