Hi! What you are experiencing with family and friends is not unusual as you read through posts on here. They are all in their own world, don't want to acknowledge your condition as they haven't digested the information themselves; just thoughtless! Don't take it to heart as it doesn't help you to come to terms with where you are at when you are worrying about others! Time for you now.
You have this forum with all the info on it as well as groups that are suitable for you.

There is a phone number which you may find useful on the link above.
Good luck with treatment, Take Care
