Help Jalen hear at home!!!

Hello, my name is Jalen Williams I'm a 14yr old boy who was born with a bilateral hearing loss. At school I use a system called a FM transmitter. The Isense micro is my ear piece and the Smartlink is the transmitter (a microphone that each of my teachers wear so I can hear them) without this system it is difficult for me to hear. Today my mom and Mrs. Olsen (my hearing teacher who has been with my case since the beginning) took me to an audiologist because I have noticed I'm not hearing well out of my good ear. Long story short......my hearing in "my good ear" has diminished! ! Since my moms insurance already covered the cost for my FM at school, they will not cover for me to have one at home! I need this so my right ear is not straining so hard and I would like to be able to hear at home too!! The cost of the FM is obviously not cheap so we cant just go buy it. Please help me and my family, it would be a system that I can use for many years to come (unless/until I lose my hearing). It would make home life as easy as school if I had a hearing device. Hearing aids do not benefit me because unfortunately with me being born DEAF there is no sound frequency to travel from ear to ear seeing my left ear is 'dead'.
Thank you for reading my story.....
