It is not a negative refelction on you if this site or it's members are a trigger dan, there is no blame to be placed.
During my time here, I've had to say goodbye to few friends for this very reason, so i understand why you feel you have to leave, but I will miss you, and hopefully we'll still have FB?
You're a good friend Dan, even if you can't see it, and I hope you are able to carry that with you on your journey
