I think the right audience might just be you, and that's ok if it is.
There are two main ways that fiction deals with mental struggles, one is talking to those living it, the other is talking to those living around it, and it is the responsibility of both to do as little harm as possible while being true. You've realised that if you were to show a wider audience what you wrote in it's current state, it could do that harm. Currently, your work is for you.
There's this saying when it comes to your thoughts and feelings, people you don't know get the published version, your wider circle gets the manuscript, your closest friends get your best second draft and your therapist gets the first ink on the blank page. All of them say the same thing at their core but when you aren't sure how things are going to be received, it's wise to do a couple of drafts. Currently you're somewhere around draft 2. There is a way of keeping the feelings real and have them speak to people all the while not pushing them to harm, and you will find it.
You can use widespread tools like trigger warnings for common triggers that appear depicted or mentionned in the text (common extreme triggers include rape, depression, suicide, school massacres - by knife or gun depending on country-, incest, death of a child, miscarrage and domestic violence) that will allow people who have those triggers to decide if they're in a place where this sort of thing is safe for them to consume or come back to it later. You can also rework your language using metaphors. Metaphors can sometimes say things more truthfully while also allowing things to be said in a way that is less harmful than just straight out saying the first thing that comes to mind.
