I guess I'm just being childish about all this. This sucks and nothing's gonna make it not suck. Crappy reality to have to accept, but that's life, and it could be worse, right?
I don't think you're being childish. Your life could be worse, but putting your experience on a spectrum of all possible experiences probably isn't helpful. You don't have to ponder your suffering relative to all possibility. Your suffering is yours. It's a big deal because it is your life, your experience. And that does, indeed, suck.
I agree with Ragdoll that it can get better, though. You have control of what happens next in your journey. You can choose to fight to get better--to manage your PTSD and quell the burn your experiences left you with. My T always says that I will always have a scar, but I don't need to have a gaping, festering wound forever.
