first off all, i honestly think it was a pretty bad decision to post it on the forums, i know you were looking for help, but as you can read some people dont give a damn bout helping you and rather say their own opinion bout specific parts of your problem.
second, i want to compliment you for being so strong, i´m also in an over-dramatic family and have some over-dramatic friends and i´m unfortunate too say i couldnt handle it. if youre heading down this road youve got to seek help, speaking to ur doctor, you cant help your family i you cant help yourself.
for the other parts of your problems, you need to stop and think about what you think is best to do, because in the end, everyone´s opinion and advice doesnt have to be yours.
