Hi and welcome, @Lilly6 ! This is a good place for when you want to talk, so it's good you've joined.
I'm sorry to hear about your trauma. A lot of people here can relate, including me.
I hope you will feel that you can share with your therapist soon...I know I've received a lot of healing by being able to work through my complex childhood trauma with my therapist over the last 5 years. I don't think it can ever be fully healed, that's not possible I don't think, but a lot of progress can be made.
I am sad to think you're thinking of suicide. I'm wondering if you know the crisis line numbers? Lifeline 13 11 1 4, and Suicide Call Back Service: 1300 659 467.
Also, I am wondering if you are on any psych medication at all? No medication names are allowed here, but if you are feeling suicidal then meds might be a good option. Do you have a supportive GP?
People here do understand how you feel, even about the SI (suicidal ideation), sadly. I hope you can find a bit of relief by being able to write about how you're feeling.
A handy forum tip is to type @ and then click on a member's name who you want to reply to - that way they'll get a notification that you're speaking to them - like I did for you above.
