In 2012 I had a serious withdrawel syndrome (Effexor/SSRI), an abortion, and the love of my life suddenly left me. All in one week. My doctor told me to slow down and rest. Focus on myself instead of using energy on others (especially my mum, having a chronic disease, very demanding).
I had to tell my mum to give me space. I needed some time on my own. I couldn't be there for her all the time.
She didn't understand. She couldn't relate. She got angry and came bothering me as nothing had happened. Eventually I screamed at her, furiously. Told her I didn't wanna live anymore.
Bang! 3 hours later, the psyc ward came to my house, forced themselves in and drove me to a psyciatric hospital (first and last time).
That's my story, and personally I would NEVER tell anyone directly that I want to ctb.
My best luck to you.
Lots of love
