Hi. From what you have mentioned, it seems that it is social anxiety which is a bigger concern for you rather than depression. You are right in saying that anxiety and depression will affect your life and it's high time you start acting to end it. Please do consult a psychiatrist and get yourself evaluated. Accordingly, treatment in form of medications and psychotherapy can be initiated.
Next Steps
Please seek a psychiatric consultation.
