Trust, I trust everyone to a certain degree, mainly because I know they are afraid to get themselves hurt, so that's on a primal level. I've never trusted my battle buddies with every fiber of my being like you claim, not all were capable to the right/left of me, some needed some serious looking after. They may have had my back but, I didn't rely on it even though that's what I was trained to do.
I have some serious trust issues, so it's not going to be so easy for me to just lower my standards, i wish i could and have also tried, but I have the strong tendency to put my guard back up when i wake up in the morning.
So, do you trust people or not trust people, that is the question.
Mate, your new to the forum and very welcome so I will tell you this. The members of the forum that have been around a while have trust issues with new people joining. You see, we have had all types of people on here from university graduates, to reporters, to trolls, trying to disrupt our forum, so it takes a while for us to trust new people 100%. We listen to you and give you advice, but you will find that some of the guys and gals on here might dissect your post's like I have done.
I still have trouble meeting new people, and most of my friends go way back. I really don't think that will ever change now. I like to keep by myself and keep people at arms length, or in the next room.
I do want to meet the guys on this forum one day, one day. Maybe you will be one in the end.
The biggest problem we all face is the fact that PTSD is a very, very lonely disorder. You can walk past a person in the street and they have no idea you are plagued with it. They might say hello and you will not hear.
You could be in a room full of friends and family, but you will still feel very alone.
Keep asking questions mate, it helps.
