Get you're friend right here, right now to see there are people who understand and can help.
I have prodded on in life for many years, probably 13+ because,
I DIDN'T want people to think I wasn't normal - bad move!
The shame/weakness/stigma I THOUGHT would be associated with it - no-one can recover from somethnig when they are in denial of having problems.
My story is not one many can reate to, so I also thought no-one would understand me - wrong again.
I didn't want to be labelled.
I could go on and on. Bottom line was I HAD to accept I had issues and so I threw the towel in when it simply became too much for me to supress. I stopped PRETENDING to eveyone that I was happy and normal.
Only now can I move on. In hindsight, I wish I had done something much, much sooner. I urge your friend to do so too. It's a lonely, painful life putting up a front. And the funny thing is, now that I have come clean to family and openly admit that I am mad..............they don't believe me. So although I have problems, they aren't as abnormal as I think they are, if that makes sense!
Welcome to you, and your friend.
Recovery IS possible, especially with knowledge of the condition, acceptance and perserverance.
