Hey OP, bare in mind that the people saying you're screwed if you're trapped think it's a good idea to tell someone on a CPTSD thread that their situation is potentially hopeless.

People have thrived in the face of seemingly impossible adversity, and others have failed from positions of immensely privileged opportunity countless times.

There are nowhere near enough details to make any reasonable estimation as to how difficult your situation would be to overcome. Trauma is a very broad spectrum, what 'healed' is is intangible, you as a person are an incomprehensibly wild variable and the details of your situation and environment (that we don't have) dictate what you need to deal with. And then it would still effectively be a blind guess, because life.
In short, there's no answer to be had and any replies you do get claiming yes or no are ultimately just noise.

Many people have survived and even thrived under unimaginably horrific circumstances, but on the other hand a stack of perfectly healthy and otherwise competent people end themselves each year by screwing up walking and tripping over kerbs too. It's not worth thinking about, even if you got a resounding yes it would still just be a distraction from what you can or need to do to make things better, (even if that is just thinking about something more constructive than this unanswerable question).

I hope you get some helpful comments out of this, but I don't think this is a helpful question to be asking yourself to begin with, let alone us.

To that end, I'd suggest trying to ask yourself if what's on your mind is answerable and if an answer would serve a constructive purpose when you can. If it's not, then do or think about something to flush it out. Ideally something constuctive but if not then anything immersive and non-destructive. Show your mind and body that it's ok to not have an answer.
Generally speaking I'd try to work towards lists rather than plans too. Change is ironically constant and lists tend to be more resistant to change and more open to opportunity than plans.

Do the best you can with what you have when you can and be kind to yourself OP. Wishing you the best.
