Well at least you know what triggered you,so now you can maybe come up with some ways to deal with similar triggers in the future.Just knowing things that have triggered you is helpful.It may not change your reactions,but at least you can tell yourself "ok,I have been triggered,I know these feelings will eventually pass".

That's the only way I can get through sometimes,is by telling myself ok,watching that video on Facebook has triggered me,this will eventually pass,I just need to take care of myself and ride it out".

I personally think it's good to keep pushing yourself,the more you do,the easier it will get.Plus,reading all you can about PTSD helps too.

I noticed on Amazon there's a new Complex PTSD workbook,looks like it would be really helpful.
