I am in psychodynamic therapy for trauma (diagnosed with PTSD along with some other things... Mostly cured now ).
It worked for me. However, and this is a big however, it takes time- I pay out of pocket too, twice a week for just over 7years now and I still am not finished... The cost of therapy should be something you can work in to your monthly budget.

Modalities are of significance but I think that the most important thing is how you and your T "click"- been to several Ts till I found one I didnt hate
