Usually physical symptoms are the first sign that you have developed an anxiety disorder. When your nervousness tends to cause:
- Rapid heartbeat
- Severe muscle tension
- Weakness
- Nausea or feelings of illness
These are often a sign that your anxiety is getting worse. Furthermore, those with anxiety often have thoughts that cascade to worst case scenarios. They cannot control a nervous thought themselves, and may even have flashes of worst-case-scenario thinking that no one can talk them out of.
