Welcome to the forum. I am new here as well and a fellow LEO. You are not alone, though if you are like me, you still feel that you are.

I believe that the hardest thing for those of us in law enforcement is to open up enough so that others can help us. We are the helpers, we are not used to being helped. I know our training makes us stuff it inside and keep it there. For me, keeping it inside just made me crawl into a bottle and ruin my marriage.

Like you, I functioned fairly well at work and just kept going. I didn't acknowledge the changes within myself though until my world came crashing down. I am now on the road to recovery.

Feeling alienated at work is common. As stated here previously, "if you don't have it, you can't understand it". Also with the typical LEO they don't want to acknowledge that they one day too could be in your shoes.

I hope that with the PTSD diagnosis you are now getting counselling. From what I have read here and experienced first hand, different strategies work for different people. It will take some time to sort out what is best for you.

Good luck in your journey Brother.
