Hi Meg I am new too and have been made to feel welcome here,I was greeted by folks who seem to really care about each other. I understand isolation very well, I am alone even in a room full of people.I am hopeful that over time, I will be able to connect with my family and others in a personal way. I find it impossable to trust people and keep them at arms length, it is very hard for even my wife to understand my PTSD and she knows what I have seen and been through. Friends, I really dont have any because of the fact that I probably would not make a very good one. I understand the way you feel and I hope you find peace here among friends.:)
