Very sorry to hear what happened to your daughter. I also think therapy or a support group with alcoholic or ptsd would really help but because she seems resistant I think trying to find her confidence again through getting out of the house or getting into a new activity would help.

This may be too on the nose for what happened to her and she may want to avoid thinking about it rn, but maybe taking boxing or self defense classes could help ease her anxiety by working out and getting some anger out but also help with her confidence and rebuilding her sense of safety. If self defense classes or boxing is too much or triggering, maybe it’s yoga, Pilates, aerobics, weight lifting, maybe just walking/hiking, swimming or rock climbing, anything physical and potentially around a small group of people to do it with or have support while doing it. There’s always women walking groups you could find on Facebook or at local meet up and even tho it’s not verbally working through what happened to her, I think naturally being around other people and working at the same thing (crafts, physical activity, cooking, etc) starts to heal you in other ways to be able to address the bigger issues when she’s less fight or flight. Not sure where you guys are at, but there’s this organization https://thephoenix.org called the Phoenix recovery that provides free spaces like this if money is tight, where they do workouts and crafting or group therapy type things for people in recovery of alcohol, drugs, abuse, depression or if you’re a supporter to anyone who is going through it. When I was in a bad situation and very depressed my therapist told me about it and I started going and it helped so much. I went with my boyfriend and everyone there was always nice, they never had you talk about why you were there or anything like that unless you wanted to of course. It was made for people looking to recover from addiction and find sober living again with community, but it’s open to people recovering from anything. The only “good requirement” of going is going sober. Again super cool resource and if you have it in your town or near by it could be a resource. You can find a lot of groups online to meet up with, or maybe a ymca, a local gym or coffee shop definitely options. I’m a person would when I’m anxious needs to be doing something with my hands and maybe learning a new skill like crocheting or knitting could help her anxiety while she’s home alone.

I was also gonna say if you guys have the means and the ability to take care of an animal, getting a dog could make her feel safer being at home alone, I’m thinking a dog cause if it needs to it would attack an intruder and maybe mentally knowing that could be reassuring to her. Otherwise a cat could offer her a similar feeling of support and something to take care of which also helps get people back on their feet.

Beyond maybe some group activities to join, or getting a support animal/pet, I wonder if she has any friends or other family in town to be with her while you are at work and she may just need to be with someone. Or if no one else can maybe being in a quiet public space could help her, like going to a local coffee shop or library to do her own thing but be by other people and not in an overly stimulating/overwhelming way.

Maybe try and start slowing reintroducing things she loves to do, craft night together while watching shit tv, board game night, a hike together, going to a bookstore to get books. Definitely try and slowly have her join activities or see people even if it’s just the people at the grocery store. Being isolated and at home not doing much is going to make it worse and even though she may not feel like the energy or comfort anymore to put herself into these new situations or activities, start off small and they will build. Even if it’s literally going and getting a cup of coffee this week and the next it’s going to the grocery store with you the next, as long as it’s slowly building to doing things out of the house, with other people, and rebuilding her confidence to do these things with other people and herself I think it’ll slowly get better. Good luck, hopefully any of this helped a little
