Social Anxiety Disorder

Thanks for your post.  First of all, I would recommend you make an appointment with your general practitioner.  Find out if you have any medical issues that could be going on that could be contributing to this.  Once a Urinary Tract Infection or other physical issues can be ruled out, then you can start thinking about psychological causes for this. 

Based on what you've described, it sounds like you might be experiencing some social anxiety.  It sounds like you're afraid of something embarrassing happening when you've in public.  This is one of the main symptoms of social anxiety.  Do you feel anything else in your body going on like sweaty palms, increased blood pressure/heart rate, nervousness, or flushed face?  These could also be indicators of anxiety.  The various forms of anxiety are very common and can be treated with therapy.  Again, I highly recommend you see a physician first.  After you get cleared of any medical issues, it could benefit you to see a therapist to talk what's going on.  If you're in the Los Angeles area, I would be happy to help you: www.drlanichin.com.  If not, there are other mental health professionals that can help you who are closer to where you live.  Therapy can be a highly effective way to explore what's making you anxious and you can also learn different ways to cope such as breathing exercises, mindfulness techniques, and meditation.  Good luck to you and I hope you find something that works to help you feel better.
