((((Faint))))
I am sorry that your Psych (psychiatrist, I take it?) or pDoc isn't working with you on how to get through life. Flashbacks are a problem when they lead to dissociation, but how in the heck are you supposed to deal with one aspect without dealing with the main cause of your problems?? I don't get it!

Aaaargh!
There are online groups that offer live support, but their hours are limited. Check out the link below...
SuicideHotlines.net - Text-Only Hotline Listings For Suicide Prevention & Emotional Crisis
Otherwise, there is Suicide Prevention available through this site...
National Suicide Prevention Lifeline - Lifeline Crisis Chat
I've called the number for the suicide prevention hotline, Lifeline, before...and they were very kind and supportive. I would imagine that their online care is similar.
