Just like a thriving relationship it takes a little elbow grease to find "the one". When you do find them, you'll see changes and results that are positive to your growth as a person.
And isn't that what we all came here for?
First things first
What do you want to go to a therapist for? Different therapists special in different things such as: anxiety, depression etc. When you figure that out you can narrow down who you want to go to. Most therapists have profiles on their respective sites where you can find out more about them, things they enjoy, accreditations and more. These are very important in finding a therapist that resonates with you and your needs.
Find options
The one, doesn't have to mean the first one right out the box. Many therapists have consultations or intakes, some of which are free that you can use up. Utilize your resources! Sometimes your work benefits will include free sessions as well. By making good use of these you can find out if your therapist is right for you for the long haul.
What to look for
Do you feel comfortable around this person? Do you feel like they understand and are striving to help you become a better person? It's one thing if they're listening, but it's something else if they play an active part in empowering you to seek clarity within yourself and what you want out of life and situations. Talk therapy is great, but you're also evolving as a person when you apply the changes you and your therapist work through.
Lastly, if you feel a therapist isn't working out, you have the power to say so. The connection is a two way street. You are never stuck anywhere. There's always room to grow even if that means letting go.
