Sarah - I felt so sad and helpless reading your posts. Your pain was palpable, and you are so brave to have reached out for help, including now getting to a safe place, where you can get the support you have been asking for so long and so eloquently.
Thank goodness that help has arrived before it was too late. I really do feel that, for today, the main focus should be on finding another solution for the care of your relative. Taking on that responsibility has been too heavy a burden for you to carry - one I suspect you should never have been asked to shoulder, and equally I suspect it's not going to get any lighter. I hope and pray that you can find the strength and support to walk away from him, and I feel sure that handling your weight and diabetes issues will become easier as a result. I may be wrong, but I can imagine how these three things are connected and why you felt it had become impossible to continue.
Please believe that, although we have never met you, there are so many of us here who can understand how you feel and really, truly want you to win. We genuinely care about what happens to you and we want to offer help and support - even if it's only to let you know that we hear you and have the time to listen and understand - because in many cases we could be in your shoes and need to believe that there would be someone who would care about and want to help us, too.
Sending you huge hugs and strength across the airwaves.
