Hi @Lookatthesea71 welcome to the forums! I hope you can find the support and connection here that helps both you and your cousin.
Reading your post I can identify with a lot of what you've spoken about. I have ptsd, or complex ptsd to be exact. It can be very debilitating and it sounds as if your cousin is truly struggling at the moment.
Bless you for being there for her and offering support. You are an angel. I can tell you from personal experience that ptsd can make you extremely anxious about everything. I know when I was really struggling I found it very difficult to even deal with basic tasks like cooking and cleaning and trying to stick to a schedule just made me all the more anxious and I'd beat myself up if I couldn't accomplish a task.
Add to that the fact your cousin has just moved into a new city and I'd guess her anxiety & ptsd has gone into overdrive.
So first of all, do you know if she has found or been to a GP? Or perhaps looked for a therapist? Helping her to find these support networks is a really great way of helping her and also showing her how much you care & support her. It is a difficult conversation to have, so go slowly. But communication between you is vital, both for your cousin, but also for your personal mental health and well-being. @Shaz51 is an amazing carer and she may be able to offer advice on how to start this conversation and also give you strategies to help you also.
As far as arranging the house goes. Perhaps mentioned to your cousin that you can see how anxious she is feeling about organising the house and in general and ask her if there is anything that she thinks she might be able to help with. The key is not to overwhelm her or shut her down. If she finds there are things that she can do, then she'll gain confidence and be able to take on more but it may be a very slow process so you may need to be patient with her.
Also if having a direct conversation shuts her down, maybe put on a movie one night and just start chatting about random things and she may begin to open up that way.
The crux of ptsd is that when an episode hits you feel extremely unsafe, overwhelmed by fear and crippled by anxiety. So if you can make her feel safe in your house it will go a long way towards helping her to cope better.
I hope that all makes sense and helps in someway. I wish you all the best, feel free to stop by the forums anytime you need support. And please feel free to tag me into your post by using @bipolarbunny if you have any other questions or just need someone to listen.
Take care & all the best xx
