There are many, many reasons, not least of which are the desire to help
people; to give back to those people who helped them in their own time of
need; and to develop self-understanding. But there is a reason which is so
obvious that I think a lot of people forget all about it. Having experienced
their own emotional difficulties, challenges, issues, and losses, people who
go into mental health professional are sensitised to how
significantly mental health issues can affect our lives. They are, in turn,
sensitised to the need for people who can help others navigate their complex
emotional difficulties. For those who’ve never experienced significant
emotional difficulties (eg, depression) or traumas (eg, rape), it doesn’t
really cross their minds that such difficulties 1. exist; 2. can be
disrupting to one’s everyday life; and 3. require the training of people who
can help sufferers cope.
