Are you still in therapy?
This sounds serious and like you need professional help.
If you can find an EMDR therapist, I'd give it a go--it can be really helpful triage for trauma.
One of my children got really sick in 2006 (seizures) and it really set the ball rolling for me, trauma-wise, I wonder if that wasn't sorta "the beginning of the end" for you. I believe trauma spawns more trauma.
Please get help. Life sometimes seems so bleak but it doesn't have to be and suicidal thoughts are not something you should ignore.
I´m still in therapy with my Pscychogist but I am thinking of meeting a doctor to get medicine. I´m really thinking I will be needing drugs to help me. I know all the "by the book" solutions but it is not enough.
