Woke up this morning with nasty cough, with taste of blood at back of throat

[Hoover1979]

Before I rush to a doctor and look like a hypochondriac I thought I'd shoot a question here:

I woke up this morning and I have been couching/gaging all morning and can taste blood in the back of my throat, I have not coughed up any blood though.

I have been trying to quit smoking since 2011 and have been a smoker since 1991.
I am also on SR Hydromorphone (Jurnisa) for severe chronic back pain.
I am also on 800Mg Carbamazapine (as a Mood stabilizer NOT for Epilepsy)
As well as Mirtazepine (for chronic Clinical Depression)
And Atenolol for mild Hypertension.

Anyhoo, as of this morning I have been hacking up a storm, as of 2 hours from waking up I developed a sore throat (I believe from the hard coughing)  I have not coughed anything up but the coughing gets so hard it becomes dry-reacing frequently.

And that taste of blood waay down in the back of my throat is ever present after each cough.

As I have depression and mood disorder, I don't want to go straight to the doc as quite often individuals with mental health issues don't get taken seriously here in Australia, quite often I would get told "Go to your psychaitrist" as if I am crazy.  and in the past I ended up in trouble with serious health issues that went undiagnosed simply because some peanut G.P. thought it was all in my head, until I ended up in hospital sometimes in quite serious condition.

So I was wondering if someone who understands this coughing issue could be could shoot me an answer first.

I am meant to go to University tomorrow (I am studying for a Psychology Degree) and I want to be at my peak for study if at all possible.

I don't know if this is related or if it is because of yesterdays Tech work on my PC, my left eye is stinging under the left lower lid.  This has been happening only for the last couple of mins. and started after my Original Post.
