You haven't terminated--your therapy was stopped. So emotionally/psychologically you're still in the process, but without the sessions. That's a very different place to be than "finished."

If you can't continue with someone, you could try free support groups, or journaling, especially on a fixed schedule, as though it were a therapy session. Write out sessions, taking the role of your T as well as yourself. Although I was ready to finish therapy, it ended abruptly and in an unexpected way, so I found the journaling helped a lot. Even though now many years later I have contact with my former T, our relationship is not about therapy, so I continue to journal intensively a couple of times a year. It keeps me in touch with myself.
