If you live in a metro area, look for hospitals that run CBT/DBT/group therapy sessions. That's another way to get started. If you have insurance, that helps.

If you don't have insurance, consider looking at your background and find a 12-step program that fits. ACA (adult children of alcoholics, but it also considers family dysfunction) is one example. It doesn't benefit from having a trained therapist, but it's effectively free group therapy.
