Hi Tam Dog,
Welcome to the community here. I would like to suggest that you go to a Dr and tell them exactly how you are feeling so you can receive a diagnosis.
If you feel uncomfortable saying the words, then write it all down and hand the paper to the Dr.
You could also Google symptoms of depression and anxiety and write down what relates to you if you don't have the words yourself.
Your Dr will be able to help you once yo have a diagnosis. There are so many strategies that will help you to cope with whatever the Dr decides yo may have.
If you do have a mental illness, the main thing to realise is the Dr may give you a name of an illness, that does not mean there is no hope!
I am also wondering if you have had any grief counselling after your brother took his own life. That must have been very tragic. You might like to Google unresolved grief as well. I have worked through grief issues and found it beneficial.
Getting an accurate diagnosis is a great first step!
There is certainly a lot of information on this forum and on the Beyond Blue website about depression and anxiety. Knowing definitely what is going on will help!
Cheers for now from Dools
