Hey AL,
Well... I hate therapy. I'm still going and I'm seeing a very good trauma therapist... but in a way, I've found the most helpful things have been things I've been doing on my own. That being said, I'm still very much in the middle of the process (I was just diagnosed officially with PTSD from complex childhood trauma in September of 2013) and y'know, time will tell if anything I've done is really effective.
I've been kinda where you are... I had a different persona for dealing with work, dealing with family, dealing with friends, etc. I was the consummate actress and highly respected in all of those areas. But that's unsustainable. You can only do that for so long and it takes up A LOT of energy. Emotions can only be buried so long... they'll come back up sooner or later, usually when you least want them to. The longer you go without directly dealing with PTSD, the worse it gets. These are just the facts of PTSD. So... really, I'm only repeating what I've had to tell myself over and over... bad coping mechanisms are just that... BAD coping mechanisms. They're called that because while they work, they don't work long term, they're detrimental to your health and they don't ever get the monkey off your back... that is, that don't actually resolve any trauma.
So... I mean, I am DEFINITELY no expert, but there are a lot of things that you can do even without a therapist to improve your life and deal with your trauma. What I'm finding, very much, is because my trauma started at age 2-1/2, that my biggest problems are related to not having one good enough parent around, having an undefined sense of self, lacking internal opinions and motivations (being a people pleaser, basing my responses, pretty much my whole persona, on who I'm talking to, etc.) and dealing with childhood neglect. That stuff is all extremely hard to deal with, and I'm not sure it can be successfully dealt with without a therapist. And while the straight forward stuff... dealing with trauma, can actually be done on your own, I think, it's so totally fraught with peril. Dealing with all of those emotions and terrible situations... it can cause serious depression, suicidal thoughts, outbursts of emotion, etc. You can definitely lose your way during the process. And the plain fact of the matter is... it's best to have someone there to keep you on track and give you perspective. That's where a therapist comes in.
Anyways... the number one thing you can do at this point (without therapy)... is to just educate yourself. Read, read, read about PTSD. This forum is awesome, there's lots of good information on the web, there are lots of good books. If you can't do therapy, then don't do therapy right now. I really, really do understand the $$$ issue. But, well... I'm not good at tough love or anything, I'm just trying to give you the facts... you can't bury PTSD forever, the amount of energy it takes is unsustainable. Sooner or later, something has to give. And the longer you wait to deal with it, the worse it gets.
I really hope this helps. This is a subject where I have a lot of opinions. It's a complicated subject... and well, I'm so prone to really long responses... I hope there's something in this abbreviated response to help you. I do respect your position... hell, I've been there myself and I've made similar choices in the past.
Be well,
