Why inquest is public?

When I lost James to suicide I had to give a statement to police. It was 2020, Covid19 lockdown time... the statment was over phone. I was in shock with what had happened. English is not my first language. Looking back, Covid or not Covid the police should had come to be to take the statement and with them a mental health counselor... I wasn't given any support from the police. I was asked a statement by the phone, told that just the coroner and the police would read it... Which wasn't correct... They wanted to know how he was during his last months, and made me tell very personal things in that statement, but I wnated to help to find out what had happened, what made him do that... also, I was assure all was private, just between me, the police and the coroner... Then I find out his mother had access to my statement, and that others could request the paperwork for his inquest, because it was public... That my statement could be read in the court and that even the press could be there, because inquests are open to the press!!! I was desperated... I didn't want others to know about our private lives, I already felt so violated when I found out his mother had access to my statement and had talked about what was there with some of his friends (that is how I found out)... I went to my WAY (widowed and young) friends and asked what I could do, why inquests is public? Like me, others went through the same trauma and had to deal with an inquest. They told me to contact the coroner and explain my concerns, ask not to read my statement... The coroner was lovely and, at least someone was human to me in all this process, my statement wasn't read in the court and in the future documents about his death (in case someone asked to have access), the private parts of my statement were censored, so no one could read. But why to make us, the ones that are already suffering with this terrivel loss, grief and trauma, go through even more trauma?! Since 1961 suicide is not a crime in the UK! Why then make us go through an inquest that doesn't give any answers but brings even more pain and trauma? Why let the press be present? Why the most traumatic event of my life is inportant to people that don't even know me, James or our families?! Why is this so important that needs to have press coverage? Why a so called "journalist" though that was ok that after the inquest (that he assisted by video call, again why?!) to stalked me on Facebook and message me on Messanger asking comments and photos?! Why that "journalist" had to write an article about the inquest and put where we lived and added both of our names? Why? What can we do to at least make the suicide death inquest private?
