I learned as I was calling around to find support that the only support groups made available for ptsd issues were strictly military related, but eventually, the local sexual and domestic violence shelter created a space for folks to meet once a week.
One of the community outreach hospital staff I spoke to in trying to find options was really pissed when she realized how little is made available to help address one of the biggest community issues, and she continued to thank me for making her so painfully aware.
Keep reaching out, keep asking, and call the shelters in your community, if there are any. If they never have requests for it, they need not follow through. They still may not, but you never know.
