I've thought about getting in touch with a therapist from long ago, who I ended on very good terms with. Nothing to do with New Years specifically, but I've been considering it from time to time for years. I have her current email address, and I think she'd respond well to a message updating her on what I'm up to, saying I'm doing well, thanking her for helping make my current successes possible. I always stop myself before actually doing it though, because while I'm mostly sure I'd be fine with whatever response or lack of response I got, I'm not entirely sure.
