People come to counselling for a very diverse range of reasons and everyone's experience of counselling differs because of this. Some people come to talk with specific issues in mind such as depression, relationship issues, anxiety, bereavement etc. Others come with no sense of what is wrong, they just feel that something isn't right.
The counselling space can offer you a non-judgemental and confidential setting to explore your thoughts and feelings. It can offer you a deeper insight into your relationships and why you behave in the way that you do. It's a space where you can look back at the past and look forward to the future.
Perhaps most importantly it gives you an opportunity to be really listened to without advice giving or interruption.
