Vanilla, I am so sorry that you are feeling very low and things are moving very slowly for you. No, you aren't a fraud and you can post wherever you want to and get support from all of us.
I'm sorry about your ma's condition and maybe your pa feels it is for the best to allow her to come home and live out her days in the comfort of her own home and surroundings.
I'm so sorry that your lung condition isn't improving quicker. Things always look worse when we are feeling under the weather. Have you spoken to your lawyer about the Fins and the Divorce? Maybe it's time to start pushing for these things to happen a bit (that is, if you are up to it).
Please take care of yourself. I know things look bleak at the moment, but I'm hoping and praying that the light at the end of tunnel will be there soon for you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
