''I dont know...maybe I shouldnt be here. I just didnt realize everyone that had this is much older than me. ''

Hey Anon,
First of all, Please let me say how sorry I am for your loss.
I have had PTSD since I was 18, and am 24 now. And I just wanted to say that anybody at any age can get PTSD, and I can only imagine how alone you must be feeling. Although you might think that you shouldn't be here on this website, you have just taken a very big step. In talking to others about how you truly feel, and hopefully find people who you can relate to and who can appreciate and relate to you.
And after all you have been through, I sincerely hope you can one day find the help and strength so you can start building for your future.
