TN,
The social worker might be able to help you with the stress symptoms-- their job is not to push pills. IME with a social worker, she listened and when I had experiences of getting more triggered from talking about stuff, venting-- she used those opportunities as "teachable moments', guided me into how to 'slow it down', re-ground brought me a lot of power over my symptoms, just from a few small moments of that. There's also a normal process about anxiousness, trust, agitation and the challenge of learning, re-learning patience (which I found to be really hard-- friken 'control freak' I was, still have some of those tendencies, but not so intense, manageable). IME, it's more challenging at the beginningn of things, earlier stages in recovery. Meds and getting the right ones, dosages can/do help and then can in turn, make it a little bit easier to deal with and learn new coping stuff/first aid management of OSI/ptsd symptoms etc.
Current treatment can tie you over as more is built into the treatment plan (sometimes there are small waitlists for other services)-- check out the resources others are suggesting here. You do have back-up and it looks to me that you've got some good people here who've got your back.
I'm not a CF member, I only recognize some things of the 'ride' you're in for and you will get through it. Believe it, if you don't, well sometimes it's a leap of faith (and no matter how reluctant you feel about that at this moment, now. . .

) and maybe that's all you need to know about that for now. Stay the course, the rest will take care of itself, it's a process thing. I bet you'll do a better job than I have, getting through it, coming to the other side of it. For sure. You have life of strengths and challenges and experiences far; and you are getting earlier intervention-- and that's a really good thing. Stay safe (no matter how frustrating or intense it gets or feels); Use your supports. Have "Safety/Crisis Plan" and use that-- just have to survive these parts, rougher waters.
#1 Rule: "Don't let the bastards grind you down"-- U2

;D . . . and "no quarter to stand". . . remember there always is that quarter (when you feel backed into a corner), and that small space can become big, and you're a force to be reckoned with-- good outcomes with staying the course of doing what needs to be done to be well again and stay safe.
Cheers,
