When you urgently need help, everything works. I don’t see a big difference between online and offline sessions. I think it’s just a matter of habit and personal preferences. Speaking of urgent help, my therapy started online, because I needed to urgently talk to someone about something that happened many years ago. That’s how I learned about the trauma anniversary, and only later I was figuring out how long does the anniversary effect last. Actually online therapy became a big support for me both then and now, because I’m still in the process of living through and accepting my trauma.
