Hello EddyPaddy. I am very sorry to hear this. I had tinnitus after a medication overdose, but over time my brain seemed to filter it out and I couldn't hear it any more. So I hope for the same for you. Would you feel able to talk to a doctor - just to check that the onset of tinnitus isn't being caused by something else?
And there is support such as the UK Tinnitus Society - they have a supportive helpline open until 5pm today on 0800 018 0527. If you are in another country I can find sources there, if you would like. I know I found it very hard with tinnitus at first and I had suicidal thoughts because of it, but it did improve such a lot. I never thought it would improve at the time, so I understand something of your distress. Sending best wishes to you.
