I agree with purchase. You are doing everything you can to help her, along with dealing with your own life, which is a full-time job on its own and, in reality, all you should have to deal with. I'm sure she appreciates everything you are doing and does not want you to feel guilty or stressed.
You can PM me also if you like. I haven't written much because I know you have a lot on your plate now, but I'm still here if you do want to talk.
Sending good thoughts your way. Take care.
