Hi I hope you have not self diagnosed yourself and this is diagnosis given by a professional. Every individual is different so is the treatment prescribed to them, in many cases meditation in the initial phases of depression may even worsen your symptoms.
Next Steps
Since you are apprehensive about psychiatry, I strongly recommend you visit a psychologist so that a detailed case history can be taken and you can be provided with a individualised treatment plan. Psychologist will recommend you to a psychiatrist if need be.
Health Tips
I understand what you are feeling but if you follow proper treatment you will be well soon. Remember what ever symptoms you are experiencing are just a part of a problem and will definitely settle down with treatment.
