Hello
@Jeffy L - so sorry to hear you are feeling so bad
Sounds like you are in an awful position right now and need some help. Having one problem is enough to deal with, but it seems you have had a big amount of misfortunes in a short amount of time. It means you have had really rough time, what it doesn't mean is that things cannot get better. Things can improve and you could be in a very different mindset one, two or three years from now - you could even be happy.
Do you have other health conditions than T, since you have been in dialysis? And if you do, are they treatable and in good care right now? What you do have - as you say yourself - is depression and it's a condition in itself that needs to be taken seriously. Crises like divorce and (possibly traumatizing) accident are sometimes incredibly tough to deal with, and it is absolutely
no shame to need help in handling them. Since you are already going through thoughts like "wish I was gone", I think it's extremely urgent to discuss these thoughts with someone that can help. Finding a good therapist can be a life-safer, since it can give you coping methods, new perspectives and the most important ingredient of them all: hope for the future. Change doesn't happen over night and I know that trying to hold on and find the strength to carry on can seem impossible. And it can be just that - impossible - when you are trying to battle it alone, that's what my personal experience is at least. Is reaching out to a helpline/support groups/therapist something you could consider?
Was there any trigger to your renewed tinnitus (i.e. acoustic trauma)? If not, I think it might have to a lot to do with the stress and mental anguish, it really can make T sound much louder. Once you get your mental well-being in balance, it's easier for the nervous system to get in balance as well. You could - and should - visit an ENT to check your hearing and that there is no other reason for your tinnitus. It is not likely, but no harm in checking. Since you sound to be in great despair, I think it's even more important to really get some help and support, so that your depression doesn't get any deeper. There is strength in you and I think it was a superb idea to come write here, since this community offers support and understanding. It's a good place to start to sort it all out.
