Hi,
I'm glad that you are trying to seek help. Anxiety is not an uncommon psychological condition which many people are reluctant to seek help for. In Singapore, there are GPs who have special interests in helping persons with various psychological conditions like anxiety, depression, etc.
IMH would be an excellent place to find out where you can seek help for. Both Geylang and Queenstown Polyclinics also run clinics that provide help and support for those with psychological conditions.
Thank you.
