@jl1ny I’m deeply sorry regarding your injury. I would also recommend not selling.
Give yourself time and maybe some improvement can come regarding your condition. The science of audiology and medical surgical intervention is always advancing.
My own personal story regarding the sale of a Hifi system was when my father died. We were never close, and he passed in my early 20’s and my siblings sold off everything of his. Now in my 40’s I’m in love with Hifi just as he was, and would happily box my system and save it for my child (now 1 year old) to give it to him at a later time at the very least. I deeply regret not hanging on to his system and record collection.
Your system often becomes a part of you (memories, joy, a journey, etc). Hold on to it. Hold on to your health and recovery, hold on to hope.
