Great advice from the others. I will just add my personal experience. Be ready for the initial 'hell' with T. This is unavoidable for many of us. T is so new and alien that the brain just got upset, scared, angry, anxious and depressed when it realizes that it can't shake the devil. It is worse when even the doctors say you will have to face it for life. The brain is in an overload trauma and shock over this and thus we suffer so much initially. It is understandable to have suicidal thoughts too. This is a way the brain suggesting an escape route. But don't take the bite. It will get better. Believe me. I and many others here had been there where you are.
Give it time. Your T is very new. There is no need to think of the 'end' yet. We did that like you. But very few would rush to do the unthinkable.
Mother time is an important factor of success for almost every one to get better. Some will be faster, others will be slower. But there will be progress as long as you stick to good, proven strategies. Why? Because Neural Plasticity will occur over time and our perception of T will improve over time. This happens to many people, including myself. However we just can't rush it. Trying too hard to rush it and insist on progress based our projected schedule will actually hamper the process, creating unnecessary anxiety and stress, which can aggravate T.
Try to put more positive affirmations. Instead of saying "I just can't seem to habituate"', perhaps say, "I am definitely better than the initial days even though there are setbacks. I will just stick to good, proven strategies and I believe eventually habituation will happen without me willing it". This will take pressure off the brain during setbacks to help it focus on other priorities of life. Sooner or later, even if T doesn't fade or disappear, the brain will get bored with T when it finally believes T is not a threat (as you have proven you can live a full & enjoyable life over time even with T), and with that, things will improve much faster and T's tyranny will be over sooner than you think. Positive affirmations with AAA attitude (Accept, Adjust, Adapt) will get you there eventually.
I speak from experience as my ultra high pitch T plus severe hyperacusis turned me into a mess initially. Ya, the inevitable suicidal thoughts were dangling in front of my tired and stressed out mind and I thought my future, if there is one, is doomed with endless suffering. What a lie from the T bully. Today, I live a normal, productive and absolutely enjoyable life and I wrote my success story like many others do. I list many helpful strategies to help me turn around. For brevity, I list the link below. Take good care. Your T may fade when your ear infection is over. Don't rush and stay calm and positive. God bless.
