I'm primarily on this site as a Supporter, but I also have PTSD that is mostly in remission. After spending over a decade (~1984-1996) doing various types of therapy, after six months of EMDR in 1996, I "graduated" from therapy.
Since then, I've been completely free of the most devastating symptoms, including flashbacks and constantly thinking about the abuse. Most days I'm pretty okay, and some days I'm great. There's a lot more to PTSD recovery than relief of symptoms, especially if the trauma was ongoing. Trauma messes with the way you see yourself and interact with the world. Once the symptoms aren't overwhelming, there's a lot of work to be done. Some say the work begins once the symptoms are at bay. I suspect that work will take a lifetime...
I suspect I'm always going to be more susceptible to being retraumatized by experiences (I've had a couple of instances). However, today I usually feel stable and secure in myself. People wouldn't look at me and think I have PTSD, i.e. I'm no longer an obvious basket case. I can handle most things thrown at me. Before my current relationship with someone who has active PTSD, I rarely even thought of it. I echo much of what's been said about taking care of yourself and having a toolbox to help manage life.
Doing the work can feel and be all-consuming, but you can get to the other side. I think I've come out of it a better, stronger person with experiences to share and hopefully help others. I'm still far from perfect and have my own struggles, but they're nothing like when I was in the thick of it. I wish you the best of luck on your journey.
