A have a family member who is a marriage and family therapist (MFT). She and most of her peers themselves see therapists. This is partly because people who become (good) therapists have themselves had to struggle with issues in their lives and dealt with it by experiencing therapy.

It's also a way to be able to talk to someone else about their cases. The person they go to is themselves bound by confidentiality restrictions so they can talk about whatever they need to without worrying that patients' communications will be leaked.
