Hi,
I totally get how you feel.
I come from a family where mental health issues are swept under the carpet. A proper vibe of "Take a tablet and get on with it"
My mum and most of my aunts have been on various anti depressants for years, so they think if they can cope, why shouldn't everyone else.
However, this view isn't great. I ended up diagnosed with bipolar and it's not something you can just take a tablet and carry on with.
I've come to realise that some people can't understand mental health or neourodiversity. They can be nice people but they're never going to get it. So I don't talk to them about it.
When they ask how I am I just do the, oh I'm fine, new tablets seem OK kind of thing.
If (when) I'm having issues I now talk to my psychiatrist, my husband or one of my friends who does get it.
Sadly some people just can't wrap their head around anyone who can't cope or think the way they do. So I find its best to keep it breezy with them and get support from others, either friends who get it or professionals.
