I (28M) always used to have good mental health.

I had a slight blip in uni but otherwise OK. Its ups and downs but it was stable.

Since moving home after my dad died, I've experienced a void and feelings of helplessness and emptiness. The worrying thing of recent is that in addition to these feelings - I also have recently had thoughts that it would be better for me not be alive (no plan just to confirm!!! I have not self harmed either) Also, before I forget I also have had sadness/teariness with no trigger. E. G. Before I'd cry if something I saw made me sad or an event did make me feel that way. Now it's out of my control a bit where I can just be set off by nothing. 

I don't know if this is depression. I did a phq-9 which was 8 or 9 so it is not really depressed.

I'm considering going to my GP. People who have gone to doctors about their mental health please may you confirm the process. I'm from a community (Sub-Saharan African) where depression is taboo and I won't tell anyone in my family I'm going. My friends have done it and been to therapy/had medication etc but I can't ask them as I don't want them to know I am struggling a bit/have been having thoughts of being better off dead. 

TLDR; considering going to the Dr to discuss mental health. What is the process and what should I expect?
