Critical osteoporosis. Staying at home?

Hello doctors, please help me. My name is Vignesh. I am a DMD patient, age 25. I have been using steroids for a long time. First, I used Defcort 6 mg for 5 years. After that, I used Wysolone 10 mg for about 4 and a half years. Now, for the past 3 months, I am again taking Defcort 12 mg. Currently, my bones are in a very severe osteoporosis condition. It is extremely critical. I have been bedridden for the past 5 years. For the past 5 months, I have been lying down continuously and cannot even sit. I cannot even be lifted and moved to another place. I am always in the same place I do everything while lying on the bed. Now I don’t know what to do anymore. I am staying on the 3rd floor, and I cannot even go to the hospital. My bones are very critical — even light lifting can cause fractures. Is there any way to make my bones stronger while staying at home? Please help me. I am unable to do anything. My number : nine nine five two zero seven one seven four seven please call me 🙏
