I am so very sorry for just seeing this. I pray your still here. My name is Sandy and I am a carepartner to my husband Jim who has ms. I stay home to care for him. We are still active and get out and do things as much as we can. My mom is sick too but still attempting to live on her own as much as possible. Your not letting your parents down, don't feel guilty. They know how much you love them and how you need your down time.
Feel free to ask any questions about NT or just vent it all here. We get it.
