It's not bloody fair!

I'm sitting here crying after receiving a phone call from my Superannuation Company. I put in a claim last year on my insurance. This was after my lawyers recieved a letter from them, saying I had cover.
Oops they made a mistake. The letter was wrong. No they will not honour the letter they wrote.
My claim is denied!!!
We are talking about a payment of between $8,000 & $10,000 only.
So since my Workplace incident back in 2014 - my ex employer - is not held responsible. Worksafe still won't release any report on my incident or the other 2 incidents that occurred in that workplace.
On the 25th of this month - I get my last Workcover pay - which has really equated to 60% of my part time income prior to injury.
I can't sue my employer. The laws are different for Mental Health injuries, compaired to Physical Injuries. And because I have gotten better - my percentage of incapacity has reduced & now falls below the threshold. That threshold is higher for Mental Injury compaired to a Physical Injury.
So I have lost over $30,000 of income since this workplace injury. I owe thousands in back rates to the local Council. I'm behind in all my bills. I don't have a job. I'm a single parent of a teenage boy who needs clothes and shoes. God, I need clothes. Mine are falling apart.
I start getting 'better' & think " I can do this. I can create a good new life". & then bang!!!! They kick me down again.
It feels like everh time I try and get back up - they just keep kicking and kicking and kicking.
I'm tired of being constantly kicked. I'm tired of having to constantly struggle - medically, emotionally, financially. I'm so bloody tired of having to do it all on my own.
Sometimes suicide looks so tempting. To just have it all stop. To end the pain and the struggle. To hurt no more.
I'm so bloody tired of fighting. One morw kickand I ddon't think I could get up again.
It's just not bloody fair.
