Hey man,
I know exactly how you are feeling, every day I beat myself up about damaging my hearing over a stupid alarm. I was in such a dark place. Have a look at some of my posts from 2016 and 2017, They do not make for good reading but I am sure you will understand what a state I was in.
Fast forward to today and my tinnitus has gone. It was more than a year before things started to improve and I started to feel like myself again. Now I am around 20 months from the acoustic trauma that caused all my problems and I was just thinking today about how messed up I was. I was sitting in my car, no music on and it was silent. I checked with the app on my phone and it read 26db, that's the same as my bedroom at night. No tinnitus, I tried searching for it but nope, nothing.
If you are experiencing periods of almost silence I believe yours can fade away completely too. In the mean time avoid loud noise and look after yourself. Try and relax. It will improve and things will get better but it takes time, lots of time.
I found a couple of glasses of red wine helped improved my mood in the evening when I was messed up. Just don't go overboard.
Sounds like you have a nice wee family there
I know what you mean when you say this causes problems with your relationships and your family. It's not easy to deal with but hang in there, things will get better.
