I donated because I have really appreciated reading your writing since I joined a few months ago. I feel like I know you a little bit from your stories. Moreover, my heart goes out to you after reading about how you have suffered with this undiagnosed condition for your entire life. I can't even imagine how much easier it would have been if someone had accurately diagnosed you and helped you understand how this has NOTHING to do with how much you eat or exercise. The stress and self-flagellation as a result of doctors blaming YOU for your condition seems like torture.
I hope you will get the support you need to schedule the surgery soon. I can imagine how helpless and scared (and angry!) I would be to only now learn of my diagnosis (nearly 39 years after birth!) but not have the resources to seek treatment.
