It’s been 4 days and I’m going crazy

I started having stronger tinnitus after a trumpet ensemble concert 4 days ago. It hasn’t shown any signs of improving and I’m started to go crazy always hearing it. Sometimes it even feels stronger than the first day. I went to an ENT and they told me there’s nothing I can do. Is this really just going to be my life now? Should I give up on my music teaching degree? I can’t take it and it’s only been 4 days. I can’t imagine what others are going through with this.
