Just a big hug. Those ones that makes you feel loved and translate into: "I got you!".
Please, do take care after yourself, take the meds or do the exercises you need to in order to control the emotions that can trigger the PTSD.
What are you reading lately? You know, after my mom's divorce from my aggressive idiot father, she started doing a lot of crosswords puzzle and it intrigued me. One day I asked why she was so hooked up on that and she said that it was the way she found to find peace and cope with her trauma.
Interesting was that she would do all her chores, go out, work and then when she would calm down at the end of the day, a time that she would be very stressed and nervous, she replaced with laughs and joy in doing those crossword puzzles. It made her mind to focus in something other then her trauma.
I say this because my mom was a different person every day after 5:30pm when she knew my father was coming back from work and her life would become hell. She was divorced and still had the same fear at the same time every day.
I end up sending her a lot of English language crossword puzzles and she started learning some English in that way.
