Embarrassment is just a mental state of mine. But If you do not want to stay here than your love ones will miss you and would be deeply hurt on the inside. Remember you might get a cure for your health problem , then you would have died for NOTHING for not staying here. A friend of mine had to deal with MS as well also having a cross dresser for a husband who she loved. Remember you HAVE people who love you both your mom and the people here.
I too have failing health: diabetes,DVT,had a heart attack,pain in my legs and feet because of DVT and diabetes,Inoperable kidney stone, and diabetic cirrhosis of liver. I stay here because my friends need me and I don't want to disappoint them by leaving. Some are major others are minor.
Just hang in there and LOVE yourself
