This will be my personal story that may help you a lot to continue your life after being diagnosed with PTSD. First of all, I want to tell you how I am very sorry that you have experienced something which left you this scar. Also, I want to tell you how I am proud of you that you are still here and trying everything in your power to stay on the right track. You are definitely a warrior! Therefore, I want to share some of the things that have helped me lead a functional life after being diagnosed with PTSD.
The reason. What was the reason you got PTSD? I got mine after my first born son died when he was just 6 months old. Now, two years after since he is gone, I cannot say how I don't have PTSD, but I can say how I can talk about it. You must identify the real trigger that has brought you PTSD. What was the worst scene you remember from that event? I thought for so long how that was the funeral, but later, I realized how it was the hospital and not being able to help my child. You may feel guilty, angry, or depressed, but be sure to realize why you feel that way. I felt guilty all the time but didn't know why. After I have realized that not being able to help him created me a feeling of guilt, I started moving on in some way. How? Because I shouldn't feel guilty, because it was not possible to help him. Identify your worst memories and triggers.
Don't force yourself. Everyone who is living with PTSD doesn't live a healthy life. I know that very well. You may have some problems with alcohol, pills, or you name it. You will try everything to shut down those awful pictures or voices you hear in your head constantly. Don't force yourself to become better if you are not ready for that. If you are on the antidepressant pills and wondering how you should finally cut down ''that habit'', try. But don't force yourself. It is okay to fail for a few times. I succeeded after the 4th try.
Overall, you should just go day by day. Believe how you will get better with time. And don't be desperate if that time is not tomorrow. You never know when it will come. But it will.
