If you are having a very hard time deciding what type of therapy to try, you might be best off trying an integrative therapist. This means the therapist is trained in different approaches and can create a blended approach he or she feels best suits your issues and personality.
Another option is to try a short-term therapy first. Once you have a better idea of how therapy works you might be more comfortable committing to another, longer-term form of therapy at a later date.
Remember that therapy is your choice. If you choose to try a form of therapy that in the end isn’t quite right for you, you are not obligated to continue. Have an honest chat with your therapist, who might be able to then recommend a type of therapy they feel could work better for you.
