It's been sometime since you posted and I hope by now you haven taken many steps towards healing.

PTSD, like most other physical and mental symptoms, shouldn't be put in a time frame. We tend to feel we shouldn't be experiencing it since the initial trauma happened years ago. My own experience has been there are days when I cope, and days when I don't.

As with my generation, you are fighting a second battle--getting shuffled around the VA. It takes nearly as much courage and determination to survive their tactics as it did getting through our wars.
In some ways it's harder. There is supposed to be help/respect...in short supply then and now.
The trick is not to give up. When--not if--the roadblocks come up then find the detour around it. Most likely you'll have several detours.
It's the way it is; prepare yourself for it as much as you can. Use every resource available to you to get further along in your dealings with the VA. The DAV has an excellent track record. They don't mince words; they know what usually works and the steps needed to be taken. Other organizations are as helpful.

There are medications to help you sleep. Being sleep deprived leaves most of us unable to think clearly. Jme on that statement.

It does get better; no cure but there is healing. Healing=understanding and accepting it's a condition we have but it is not our identity.

Thank you for your service to our country.
