Psychologist, therapist, social worker, counselor, and a dozen other names—they all do most of the same things. They have slightly different training in some ways, and when it comes to specifics, such as whether they are doing family therapy or addiction therapy or psychotherapy or analysis or any of hundreds of different kinds of therapies, they can be quite different.
What you need to do is interview them and ask them what their training is, what style of therapy they use, and what their philosophy is for working with clients. You probably want to limit yourself to therapists who work with stress management. But it doesn’t even have to be therapists. There are coaches and religious officials and Buddhists who provide good stress management training.
My doctor left doctoring to become a leader of a stress management clinic whose major technique is mindfulness. These days, mindfulness is probably a favorite coping technique.
You could also ask for advice here. We’ve given the same advice a hundred times over about stress management. Mindfulness. Exercise. Eating regularly. Getting proper sleep. Lots of other things people recommend. These are the same things you’ll find with a class or a therapist. You could also buy a book about it.
The best thing about a therapist is you have a live person to talk to about it. But you may want a class as well because that provides more interactive support, and you relate to classmates as well as a therapist. And they say support groups are more effective than individual therapists.
But in the end, it’s on you to find a therapist or class or situation that works for your learning style. You know yourself best, so you have to decide what you need. You can only decide after educating yourself about the options out there. Good luck.
