Welcome. We all have different stories, I'm not a veteran, but I wish you all the best. Therapy can be really really hard at first and you feel, like Rally nut said that everything's getting worse and out of control, but it really does help. Sometimes I think of it like chemo, you see people who are so ill from the treatment, comiting, losing hair, but if it works the same treatment does make them better. The other useful warning I received from a friend is that improvements don't tend to be stable and linear (you take one step forward, two back, two forward one back, things get better, then worse, then better), I have seen definite improvements but it hasn't been a stable or predictable path.
I've noticed real improvements in my life and health though and have to say it's absolutely worth facing the things that terrify you, talking about things that make you squirm and screm and cry. If you can get parts of yourself and your life back, it's worth it, and you are worth taking that effort.
Best wishes, and best of luck
