You are strong, remember that. I am actually glad that you are going in, although as some of us know, it is hard.
But I think and hope that this brings changes to your life so that you are stable and healthy. I know meds have been such a struggle for you. I can relate. So I hope that they can really spend time with you and figure out a way to save you from this nightmare you've been living.
You are very brave for accepting this step. I send you many hugs and positive thoughts.
Looking forward to hearing from you when you get home.
