Hi Gem, welcome
I'm please you are getting professional help. A big plus there.
OK, imagine you are an astronaut. You go to space then return. You tell all your family and friends...how many would be able to relate to your story?. If anyone did they would be a rarity, maybe a pilot or parachutist with imagination and intense interest.
No different to mental illness, an illness you cannot see, hear, smell, touch or taste, just an account from you and sadly it isn't enough.
My guess... 80% don't get it at all, 10% try and have limited success, 5% have extreme empathy and can help (includes many professional medical people) and 5% have a mental illness. Not good odds to get help is it?
Hence this forum and why it's so successful. You're among your own.
