I'm so sorry it's so tough for you Danny.
Crisis line staff may not understand PCS but they do understand that people are dealing with grief and despair for so many reasons, and you've been grieving for a long time.
You're not just dealing with having lost so many loved ones in your life, you've most probably been grieving the loss of your direction as well. One day you were at University and everything was on track for your professional career and the next thing you know everything changed.
I often think about all of you young people who are dealing with these dramatic changes in your lives. You have dreams and work hard to achieve them and then one day you're totally sidetracked.
I'm glad you're seeing someone tomorrow. I'm sorry you need to wait until tomorrow is all. Keep safe.
