If you feel that there are some aspects in your life that you wish to change or improve, if you feel unhappy or worried and this is making it difficult for you to enjoy your day-to-day activities, if you are disturbed by an issue which appears to be hindering your ability to concentrate and function well, if you have trouble coping with a new situation in your life or if you simply wish to express pent-up feelings and confide in someone trusted, you can seek counselling
Attempt to persuade the person in question to talk to a professional and assure them that they would not be forced to do anything against their will. Find out why they are resisting counselling and dispel any myths if present. If he/she still refuses to go for counselling and if his/her behaviour is directly affecting you, you can come in for counselling yourself to learn how to better cope with, handle and help that person.
Sometimes, people who really care about us are able to notice problems / issues that we fail to recognize for ourselves. In such a situation, there is no harm in going for counselling and sharing this openly with the counsellor. Together, you can both identify if there is a need for counselling or why others feel that you require counselling.
Any doctor would tell you that self-diagnosis is dangerous and this applies to psychological problems as well. Just as a running nose does not mean you have pneumonia, one or two symptoms taken out of context does not mean that you have depression or anxiety. If you feel unhappy or uncomfortable with your life, talk about it with a trained counsellor and focus on making yourself feel better.
