Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.

It sounds like PTSD could be a possibility but you reeeaally should try to go see a doctor. If you get really under a panic attack, call 911 or go to the ER and someone will be able to help. It's better to let the professionals diagnose something like this AND to help you get any treatment you may need.
In the meantime, HUGS, I do hope that you can get some relief just by feeling like you do belong in this great community.
PS Try some breathing exercises, they help!
