My throat tightened a little bit from anxiety and i have dry mouth a lot. can this be just anxiety or is a more serious issue?

More questions...: Have you been diagnosed with an anxiety disorder? Are you taking any prescription or over the counter medications? Do you suffer from fatigue or muscle soreness? What you are describing can be a variety of conditions or side effects. My best suggestion is to see your physician and provide your concerns with a comprehensive list if medications or drugs you use do they may evaluate the source.
