If the answer to these questions is yes, you might want to think about talking things over with a professional counsellor. A counselling relationship will help you explore some of your inner resources and better understand any worries that are preventing you from living a fuller life. I believe that we human beings are essentially social, creative and that to realise our potential can be a struggle.
My work is based on the Person Centred approach of Carl Rogers that can be summarised in his following quote:
Individuals have within themselves vast resources for self-understanding and for altering their self-concepts, basic attitude and self-directed behaviour; these resources can be tapped if a definable climate of facilitative psychological attitudes can be provided. (Rogers, 1980)
