it sounds like she was willin gto be supportive as long as you were doing what she thought was right - a good friend would have supported you in your decisons - she may not agree with them - but the support should be there - unfortunatley I think you trusted a person who had issues of her own - I am sorry you lost a friend and your peotry and diaries.
Dont let this stop you from trying again in a smaller way to trust people -
and if you should see her - just be polite - say Hi an then walk away - it sounds like its too painful a relationship to maintain
take care

When you have come to the edge of all light that you know and are about to drop off into the darkness of the unknown,
Faith is knowing One of two things will happen: There will be something solid to stand on or you will be taught to fly.
